Question

Explain the structure of a flower ​

Answer 1

Answer:

Structure of Flowers:

Flowers contain the plant's male and female reprodective organs. There are many types of flowers, but the more abvious ones are usually brightly coloured and sweet smelling to attract insects, birds even bats. These animals come to feed on the sugary nectar stored at the base of the plants.

Parts of Flowers.

•  Petals:

Petals are brightly coloured and have a scent to attract insects.

• Stamen:

The male reprouctive organ is called Stamen.

• Sepals:

Sepals protect the flower when it is in bud.

• Nectar:

Nectar is made of at the bottom of the petals. It is a sweet liquid that attracts insects.

• Carpel:

The female reproductive part called Carpel.

What are flowers?

Flowers are the reproductive structures produced by plants which belong to the group known as Angiosperms, or 'Flowering Plants'.  This group includes an enormous variety of different plants ranging from buttercups and orchids to oak trees and grasses.

STRUCTURE OF A FLOWER :

A flower is basically made up of four concentric rings of structures. There is an outer ring of modified leaves called sepals. These provide protection to the flower before it opens and are usually green. This outer ring is known as the calyx.

Inside the sepals is another ring of modified leaves called petals which are often brightly coloured. This layer is known as the corolla.

Within the corolla are one or more stamens containing pollen, which are the male reproductive structures.

In the very centre of the flower are the female reproductive organs.

Peduncle:

This is the stalk of the flower.

Receptacle:

It is that part of the flower to which the stalk is attached to. It is small and found at the centre of the base of the flower.

Sepals:

These are the small, leaf-like parts growing at the base of the petals. They form the outermost whorl of the flower. Collectively, sepals are known as the calyx. The main function of the calyx and its sepals is to protect the flower before it blossoms(in the bud stage).

Petals:

This layer lies just above the sepal layer. They are often bright in colour as their main function is to attract pollinators such as insects, butterflies etc to the flower. The petals are collectively known as the corolla.

Stamens:

These are the male parts of a flower. Many stamens are collectively known as the androecium.They are structurally divided into three parts:

▪️Filament: The part that is long and slender and attached the anther to the flower.

▪️Anthers: It is the head of the stamen and is responsible for producing the pollen which is transferred to the pistil or female parts of the same or another flower to bring about fertilization.

▪️Pistil :This forms the female parts of a flower. A collection of pistils is called the gynoecium.

Pistil consists of four parts :

1. Style : It is a long slender stalk that holds the stigma.
2. Stigma :This is found at the tip of the style. It forms the head of the pistil.
3. Ovary : They form the base of the pistil. The ovary holds the ovules.
4. Ovules :These are the egg cells of a flower. They are contained in the ovary.
