Flowers are often the most attractive part of a plant. In addition to the petals are the genitals of the plant, in which the fruits and seeds are formed as a result of fertilization.

2-stages of sexual reproduction in plants

• The male part of the flower is called ‘stamen’. male of this plant gametes Helps in the formation of and is found in pollen grains.

• The female part of the flower is called ‘carpel’. It helps in making female gametes or egg cells of the plant and is found in the ovules.

3-different parts of a flower,

, Receptacle: It is the base of the flower found on the stem or stalk of the flower. It is the receptacle itself, to which all parts of the flower are attached to it.

, Sepals: These are green leaf-like parts, which are present in the outer part of the flower. When the flower is in the form of a bud, the sepals protect it. All the sepals of a flower together are called Calyx.

, Petals: Petals are the colored leaves of flowers. All the petals of a flower are called corolla. Flower petals have fragrance and they attract insects for pollination. Their job is to protect the reproductive organs present in the central part of the flower.

, Stamens: The stamen is the male reproductive part of the plant. They are present within the ring of petals and have a short stalk with a swollen upper part. The stamen is made up of two parts – ‘Anther’ and ‘Filament’. The stalk of the stamen is called a ‘filament’ and the swollen upper part is called an anther. The anther of the stamen produces pollen grains and keeps them inside. The male gametes of the plant are found in the pollen grains. A flower has many stamens.

4-pollination

When the pollen grain from the stamen reaches the stigma of the carapace, it is called ‘pollination’. This is important because it is because of pollination that the male gamete can mate with the female gamete. Pollination occurs by insects, wind and water such as bees, butterflies and birds.

There are two types of pollination – self-pollination and cross-pollination. When pollen grains of one flower are carried to the stigma of the same flower or to the stigma of another flower of the same plant, it is called ‘self-pollination’.
