Sexual Reproduction in Flowering Plants || in Hindi for Class 10

In this biology video in Hindi for Class 10 we explained the process of sexual reproduction in flowering plants. This is a topic from chapter 8 - 'How do Organisms Reproduce' From NCERT for class 10.

Stamen : The stamen is the male reproductive part which produces pollen. A stamen typically consists of a stalk called the filament and an anther.
Pollen is a powdery substance produced by seed plants. It consists of pollen grains which produce male gametes (sperm cells).

Pistil : A pistil is the female reproductive part which typically consists of an expanded basal portion called an ovary, an elongated section called a style and an apical structure called a stigma that receives pollen.
The ovary is the enlarged basal portion containing one or more ovules. Each ovule has an egg cell.

Unisexual Flower : It contains either stamens or pistil. e.g., papaya.

Bisexual Flower : It contains both stamen and pistil. e.g., lily, rose, mustard.

Fertilisation : Agents, like wind, water or animal, transfer pollen from stamen to stigma. After the pollen lands on a suitable stigma, it has to reach the female germ-cells which are in the ovule. A tube, known as pollen tube, grows out of the pollen grain and travels through the style to reach the ovary. The male germ-cell fuses with the female gamete. This fusion of the germ-cells or fertilisation gives us the zygote which is capable of growing into a new plant. After fertilisation, the zygote divides several times to form an embryo within the ovule. The ovule develops a tough coat and is gradually converted into seed coat. The ovary grows rapidly and ripens to form a fruit.Meanwhile, the petals, sepals, stamens, style and stigma may shrivel and fall off. The seed contains the embryo which develops into a seedling under appropriate conditions. This process is known as germination.
