What is a flower?
A flower, sometimes known as a bloom or blossom , is the reproductive structure found in flowering plants (plants of the division called angiosperms).
Angiosperms - derived
from the Greek and means “seed in a vessel”.
The biological function of a
flower is to effect reproduction, usually by providing a mechanism for the
union of sperm with eggs.
What are the
parts of the flower and their function?
1. Petal (corolla) - is the colorful part of the flower.
2. Sepal (calyx) - is the green part of the flower, to protect and to cover the petal.
3. Peduncle - the stalk of a flower
4. Receptacle - the part of the flower above the peduncle
5. Ovule - the inside of ovary. If combined with pollen it becomes seed (it means that ovule is the egg).
6. Ovary - the outer of ovule.
7. Anther - has pollen in it. It is usually yellow.
8. Filament - holds the anther.
Filament + anther = stamen: the male part of the flower
9. Stigma – is the upper tip of the style on which pollen falls and develops.
10. Style - below the stigma.
Ovary + ovule + stigma + style = pistil: the female part of the flower protects the seed

The Structure of Flowers
Four kind of
modified make up a complete flower:
Ø Pistil and stamens (primary reproductive
structures)
Ø Petals and sepals (secondary structures)
Pistil – is the female reproductive structure. It has stigma, where the pollen becomes attached and germinates; a style, through which the pollen tube grows; and ovary with one or more ovules.
Stamen – is the male structure. Its
filament supports an anther, in which the pollen is formed.
The Female Reproductive Organ: The Carpel
The female parts of a flower consist of an ovary, which contains one or more ovules, a style and the stigma. The ovary is at the base of the flower.
From the ovary, extends a tubular structure called the style and on the top of the style is a surface receptive to pollen called the stigma.
The stigma can take many different forms, most of
them designed to help trap pollen. There are many variations on this basic
structural theme.
After fertilization the ovule becomes the seed and the ovary becomes the fruit.
The male parts of a flower consist of one or more stamens. Each stamen is made up
of paired anthers (sacs containing pollen) on a filament or stalk.
The anthers are the orange/yellow
structures often seen in the center of a flower.
Pollen from the anthers of one flower is
transferred to the stigma of another usually either by wind, or by animals,
especially insects.
THE DIFFERENT TYPES OF THE FLOWER
Rose
Tree Roses- these are made of hard woody stem, they need extra precaution during winters.
Tulips
Fosteriana – the structure of petals are pointed
Orchid
Miltonia- they are very warm as for as fragrance is concerned
Vandas- they looks nice while hanging with great aeration
Daisy
Dainty daisy—starts from end of winter to summer.
Lilly Flowers
Rain lily- as its name shows rain lily blossom mostly during rainy season
Calla lily- its structured like bulb, petals are moistly
Tiger lily- it’s a beautiful spices grow ditches also tiger shady
Love is like a beautiful flower which I may not touch, but whose fragrance makes the garden a place of delight just the same.
