Question

Explain briefly the different parts of a flower

Answer 1

Peduncle: The stalk of a flower. 
Receptacle: The part of a flower stalk where the parts of the flower are attached. 
Sepal: The outer parts of the flower (often green and leaf-like) that enclose a developing bud. 
Petal: The parts of a flower that are often conspicuously colored. 
Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. 
Anther: The part of the stamen where pollen is produced. 
Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma. The mature ovary is a fruit, and the mature ovule is a seed. 
Stigma: The part of the pistil where pollen germinates. 
Ovary: The enlarged basal portion of the pistil where ovules are produced.

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 centre 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 reproductive structures in higher plants are contained within flowers. Flowers have more than one petal, and the flower petals are collectively called the corolla. A flower bud is protected by green leafy structures called sepals. Collectively, all of the sepals form the calyx.

The corolla or petals are often brightly coloured with markings attractive to insects. The flowers may also be scented. For instance, Honeysuckle has showy, attractive flowers which attract insects by day. However, in the dark, their colourful show is not much use, and their heady scent then helps to attract night-flying moths.

In insect-pollinated plants, there are also usually nectaries which secrete sugary nectar, located within the flower. These provide an incentive to insects to visit the flowers. In the search for nectar, the insects will often get pollen grains caught on their bodies. This may then brush off onto the stigma of the next flower visited and in this way the flowers are pollinated.

The receptacle is the place on the stem where floral organs originate and attach.    

Answer 2

$\boxed{Question =}$

$\textbf{Explain briefly different parts of flower..??}$

$\boxed{Answer =}$

$\textbf{Flower}$ is the main reproductive part in plant. It has 4 parts namely;

1) Sepal.

2) Petals.

3) Stamen.

4) Carpel or Pistil.
----------------------------------------------------------------

1) $\underline{Sepal}$

These are green leaves present at the base of a plant. They protect the flower in bud condition. They contain chlorophyll. So, they also help in pollination.
-------------------------------------
---------

2) $\underline{Petals}$

These are coloured leaves. They attract the insects for pollination.
-------------------------------------
-------------

3) $\underline{Stamen}$

It is the male part of flower. It has two parts :-

a) A long stalk part called Filament.

b) And the lower portion is Anther. Anther contains pollen grains.
-------------------------------------
--------------

4) $\underline{Carpel}$ or $\underline{Pistil}$

It is a female part of flower. It consists of 3 parts :-

a) Upper broad portion called stigma. It reduces the pollen grains.

b) Middle thin part called Style. It transfer the pollen grains from stigma to ovule.

c) Basal swollen portion called Ovary. Ovary contains ovule which contains female gamates.
