What do you get in this chapter course?

In the course of the Biology class 12 ncert solutions chapter 2, we cover all the topics that you find in your biology book.

1. Flower – A Fascinating Organ of Angiosperms

A flower is the most colourful part of a plant. But that is not the only trait it has. The flower plays an important role in the process of reproduction.

2. Pre-fertilization: Structures and Events

Before the fertilization, the plant experiences various events that prepare it for the process. The stamen, pollen grain and other are the important factors here. Then, pollination takes place to start the process of fertilization.

·         Stamen, Microsporangium, and Pollen Grain

·         The Pistil: Megasporangium (ovule) and Embryo sac

·         Pollination

3. Double Fertilization

Double fertilization includes one female and two male parts of the flowering plants. One female gametophyte gets attached with two male gametes.

4. Post-fertilization: Structure and Events

After the completion of fertilization, the process of growth starts. The development includes the endosperm, embryo. Multiple events take place before the complete growth of the seed.

·         Endosperm

·         Embryo

·         Seed
