Class 12 Biology - Chapter 1: Sexual Reproduction in Flowering Plants
Understand the process of sexual reproduction in flowering plants in Class 12 Biology Chapter 1. Learn about pollination, fertilisation, seed formation, and apomixis.
Overview
This chapter explores the process of sexual reproduction in angiosperms. It covers the structure of flowers, development of male and female gametophytes, pollination, fertilisation, seed and fruit formation, and the significance of apomixis.
Why This Chapter Matters
Understanding sexual reproduction in flowering plants is crucial for grasping plant biology, genetics, and evolution. It also has applications in agriculture, horticulture, and plant breeding.
Real-Life Applications
- Understanding the mechanisms of pollination and fertilisation.
- Analyzing the development of seeds and fruits.
- Exploring the role of apomixis and its applications in crop production.
Skills You Will Learn
- Identifying floral structures and their functions.
- Differentiating between types of pollination.
- Explaining double fertilisation and post-fertilisation changes.

Flashcards
A: Double fertilisation involves the fusion of one male gamete with the egg (syngamy) and another with the secondary nucleus (triple fusion), forming the zygote and endosperm respectively.
A: Apomixis is a form of asexual reproduction that mimics sexual reproduction, resulting in seed formation without fertilisation.
A: Pollination can occur via agents like wind (anemophily), water (hydrophily), insects (entomophily), birds (ornithophily), and others.
