What is a Flower?
A flower is the part of the plant that makes the seeds. The main parts of a flower are the carpels and stamens. These parts are often found in the center of the flower. There are egg cells in the carpel and pollen cells in the stamen. All flowers have four basic parts: 
sepalspetalscarpels and stamen.
Different flowers have different numbers and shapes of these parts.

The Importance of a Flower
Flowers play an important role in making the life of a human being more cheerful and happy. People use flowers in several forms and on several occasions. Flowers are used as beautiful flower arrangements for decorating homes. They are also help people in proposing their partner for life, as well as flowers are used as a symbol of mourn and tribute on loved ones funeral. Apart from above said uses, there are several other uses of flowers in various activities of our daily life.

Flower Structure and Function
Andromeda Botanic Gardens

Flowering plants are the dominant type of plants on the earth today (there are about 250000 species). Flowers are therefore the most common plant organs for sexual reproduction.  
Flowers produce gametes (sex cells).
Flowers play a key role in pollination. Pollination is the transfer of pollen (containing the male 
gametes), from the anther of a flower, to the stigma (receptive surface of the female part of the
flower) of the same or a different flower.

Parts of the Flower:



Flower Part
Form and Function
Peduncle
Flower stalk.
Receptacle
Part of flower stalk, bearing the floral organs, at base of flower.
Sepal
Leaf-like structures at flower base, protects young flower bud.
Calyx
All the sepals together form the calyx.
Petal
Located in and above the sepals, often large and colourful, sometimes scented, sometimes producing nectar. Often serve to attract pollinators
 to the plant.
Corolla
All the petals together form the corolla.
Stamen
Male part of the flower, consisting of the anther and filament, makes 
pollen grains.
Filament
The stalk of the stamen which bears the anther.
Anther
The pollen bearing portion of a stamen.
Pollen 
Grains containing the male gametes. Immature male gametophyte with a protective outer covering.
Carpel\Pistil
Female part of the flower. Consisting of the stigma, style and ovary.
Stigma
Often sticky top of carpel, serves as a receptive surface for pollen grains.
Style
The stalk of a carpel, between the stigma and the ovary, through which
 the pollen tube grows.
Ovary
Enlarged base of the carpel containing the ovule or ovules. The ovary
matures to become a fruit.
Ovule
Located in the ovaries. Carries female gametes. Ovules become seeds 
on fertilization.

The sex of a flower can be described in three ways:
1.      Staminate flowers:  Flowers bearing only male sex parts. These are sometime referred 
to as "male flowers".
2.      Carpellate\Pistillate Flowers: Flowers bearing only female sex parts. These are
 sometimes referred to as "female flowers".
3.      Hermaphhrodite\Complete flowers: Flowers bearing both male and female sex parts

Quotes

“What a lovely thing a rose is!"

He walked past the couch to the open window and held up the drooping stalk of a 

moss-rose, looking down at the dainty blend of crimson and green. It was a new 
phase of his character to me, for I had never before seen him show any keen
interest in natural objects.

"There is nothing in which deduction is so necessary as religion," said he, leaning

with his back against the shutters. "It can be built up as an exact science by the 
reasoner. Our highest assurance of the goodness of Providence seems to me to
rest in the flowers. All other things, our powers, our desires, our food, are all really 
necessary for our existence in the first instance. But this rose is an extra. Its smell 
and its color are an embellishment of life, not a condition of it. It is only goodness
which gives extras, and so I say again that we have much to hope from the flowers.”
― Arthur Conan DoyleThe Naval Treaty

   “I know a bank where the wild thyme blows,
      Where oxlips and the nodding violet grows,
      Quite over-canopied with luscious woodbine,
      With sweet musk-roses and with eglantine.”
     ― 
William ShakespeareA Midsummer Night's Dream
Flowers are wonderful creation of the nature to word, which always let everyone feel positive
energy inside them. Flowers are of many colors various shapes with amazing fragrances,
different Types of Flowers have different habitats and unique features as each flower color 
shows different meaning to society e.g. white meant for peace red for love, yellow for friendship. 
Peoples love to have flowers from their garden to bed room from private offices to public
places because it just not only splash which we do but it’s beautiful part of our daily life which 
always full us with life and also motivate
with good energy.

There are wide range of flowers available in the various parts o word but some of them which are 
famous are as given below:
Roses- over than 100 of species are available of roses with different colors and sizes with attractive 
petals, most of roses are habitual to Asia few are to Europe and Africa also northern region 
of America. Some of these species are Austin, Alba, Bourbon, Buck etc.



Austin-English rose which is known for more its fragrance also called romantic flower
Alba- famous garden white rose
Bourbon- it comes in wide range of colors shapes and habitats
Buck- Comes with layered arranged petals with great combination
Grand flora- these are shrub or bushy roses with various varieties
Miniature- this is small species which can be grown in pot
Climber- it is great species to make climb on household and offices
Tree Roses- these are made of hard woody stem, they need extra precaution during winters.
Tulips – This is a beautiful species of flowers which is found on mountains Europe, Atlanta and
a lot of places around 110 species are of tulips, peoples love to have tulips around them it was 
originated from Netherlands and spread worldwide because of its goodness.

                                
In many cases flowers are borne as a group on a common stalk, called an inflorescence
They are many different types of floral inflorescences. The type of inflorescence present is
sometimes used to aid in classifying flowering plants. Below are a number of common floral 
inflorescences.


Flowers are sometimes associated with prominent, often brightly coloured leaves called bracts
In some instances (like in bougainvilleas, heliconias and  ginger lillies), the bracts are even more 
colourful and outstanding than the flowers they surround.

In the heliconia cultivar on the left, the large yellow 
and red structures are bracts, while the small
yellow structures within them are the actual flowers.
The yellow shrimp plant, has large, showy yellow bracts, and smaller white flowers.

What is the largest flower in the world?                                                                                           
   The Rafflesia arnoldii.  
The flower with the world's largest bloom is the Rafflesia arnoldii. 
This rare flower is found in the rainforests of Indonesia. It can grow
to be 3 feet across and weigh up to 15 pounds! It is a parasitic plant,
with no visible leaves, roots, or stem. It attaches itself to a host plant
to obtain water and nutrients. When in bloom, the Rafflesia   emits a repulsive odor, similar to that of rotting   meat. This odor attracts 
insects that pollinate the plant.

HOW TO PREPARE EFFECTIVE HANDOUTS


Handouts are crucial in linguistic research, so it’s important that you master this discourse genre. Here are some basic guidelines for creating an effective handout for sociocultural linguistics.
Make people pay attention to the content of the handout, not its appearance
·         Use only white paper.
·         Use a readable, ordinary font like Times or Courier. Don’t vary fonts (or font styles or sizes) for design purposes; you may alternate between a text font and a transcript font, or you may put headings in a different font/size/style, but make the text as uniform as possible. And bear in mind that most academics have poor eyesight; use at least 12 point font. If you want to shrink two portrait pages to fit one landscape page to save space, enlarge your font accordingly so that the handout text is the equivalent of 12 point.
·         Use white space judiciously; don’t cram more than you can fit into each page, and don’t leave gaping blank spots. Never double-space a handout.
Make the handout easy to navigate.
·         Match the handout order to the presentation order. Don’t make audience members flip back and forth between pages (or between handouts; you should have only one handout for your presentation). If a large transcript or table won’t fit where you want to put it, reduce its size, break it into pieces, leave white space, or restructure your presentation order. If you have an extremely long transcript that you are analyzing in detail, you may include the whole thing in an appendix, but you must repeat the excerpts you analyze within the main text of the handout.
·         Double-sided handouts are highly recommended (they’re lighter weight and save paper).
·         Always staple multipage handouts, preferably only once, in the upper left corner.
·         Include page numbers!
·         During your presentation, guide people through the handout. You may optionally refer to page/section numbers, but you absolutely must refer to example numbers, and to line numbers when used.
·         During your presentation, give people time to digest examples. Ideally play at least one or two of your examples and read the rest. If you don’t have time to play or read the whole example, try to at least read a piece of it or mention the key part of it (e.g., “In example (4), first-person pronouns occur in lines 4 and 19.”)
Elements of the handout
Title section
This occurs at the top of page 1 (and nowhere else; don’t have a header with the title on every page). This section includes more than the title. You should have the following information, typically in this order, typically centered (i.e., model it on the manuscript of the article that this presentation will eventually become): title of paper, your name, (your university affiliation and perhaps department: for conferences, job talks, etc.), your email address. It’s a marker of a newbie to put too much information in the title section; if you want to include the presentation location (e.g., the conference acronym, such as AAA or LSA) and date, you can add it in the first page header or below your email address, but don’t list the session title, organizer, etc.
Body
This can vary quite a bit, depending on the nature of your presentation. You can structure the body using headings and/or an outline format, or if your presentation is primarily data-driven, you can simply allow readers to follow along using the example numbers. Don’t overstructure your handout; one or two heading levels is the most you should use.
Quotes
You can include quotes from other researchers if relevant, but you should not number them. Cite the author, date, and page number parenthetically, and then add the full reference in your reference section at the end of the handout.
Examples
All data examples should be numbered. Tables and figures should be numbered separately from data examples. That is, if you have a table that occurs after data example (4), call it Table 1 and follow it with data example (5). Number all examples, tables, and figures using Arabic numbers only. By convention, data examples are usually numbered in parentheses above the data: (1), (2). Don’t write “example” before the example number.
Tables
Keep their design simple, and use them only for the presentation of material that won’t work better in a data example or a graphic of some kind (e.g., lists of discourse markers and their function in the discourse work well in a table; simple statistics may be best presented in a table, but often a graphic is better for this purpose). Transcripts should almost never be in tables. All tables should have clear and informative captions: not “Table 1: Codeswitching” but “Table 1: Percentage of codeswitching in narrative, by gender.” Look at examples of published tables to find an effective format. Tables are harder to design than you might think.
Figures
Figures include charts and graphics. If you have graphics, make sure they’re clearly visible on the handout. Color graphics are pretty but expensive; a clear black and white photocopy is usually fine. Like tables, figures should also have informative captions.
Transcripts
Provide line numbers for transcripts of more than a few lines (typically 5 or so). Line numbers should be Arabic numbers with no parentheses or periods. Try to format your numbering so that long lines don’t run into the numbering column or the speaker name column.
Don’t:
1   A: blahblahblahblah blahblahblahblah blahblahblahblah
blahblahblahblah blahblahblahblah.
2   B: blahblahblahblah blahblahblahblah.
Do:
1   A: blahblahblahblah blahblahblahblah blahblahblahblah
         blahblahblahblah blahblahblahblah.
2   B: blahblahblahblah blahblahblahblah.
Include only the text that you absolutely need to make your argument and use ellipses to mark omitted text; if you need to use a long transcript, highlight the material under discussion (e.g., underline or boldface, arrow in the margin).
Transcription conventions
You should list all the transcription conventions you use in the handout, and only those. To save space, you can simply cite your source for transcription conventions, if you’re using a widely known system like Jefferson’s or Du Bois’s.
References
List only the references mentioned in the presentation (orally or on the handout). These are usually no more than five or ten for a short talk, or a page for a longer talk.
