Question

Describe the various steps involved in the sexual reproduction in plants.

Answer 1

In sexually reproducing plants, flowers function as the reproductive organs.

• In flowers, male organ is the stamen and female organ is the carpel.
• Flowers which have both the male and female organs i.e. stamens and carpels are called bisexual flowers whereas flowers which have either male or female organs are called unisexual.
• Male gametes called pollen grains are produced by stamen, and carpels produce female gametes called ovules or egg cells inside ovaries.
• Fertilization takes place in the ovule where the egg cell and pollen grain fuse.
• This fertilized egg cell later develops into an embryo and the entire ovule gets converted into a seed.
• Under favourable conditions, the seed germinates to give rise to a new plant.
