FAQs on Pre-Fertilisation Structures & Events Video Lecture - Biology Class 12 - NEET

1. What are the pre-fertilisation structures in plants?
Ans. Pre-fertilisation structures in plants include the male gametophyte (pollen grain) and the female gametophyte (embryo sac) within the ovule.
2. What events occur before fertilisation in plants?
Ans. Before fertilisation in plants, events such as pollination, pollen tube formation, and the release of sperm nuclei into the embryo sac take place.
3. How does pollination contribute to pre-fertilisation in plants?
Ans. Pollination is the transfer of pollen grains from the anther to the stigma, which is essential for the initiation of fertilisation in plants.
4. What role does the male gametophyte play in pre-fertilisation structures and events?
Ans. The male gametophyte (pollen grain) contains the sperm nuclei, which are released into the embryo sac during fertilisation to fertilise the egg cell.
5. Why are pre-fertilisation structures and events crucial for plant reproduction?
Ans. Pre-fertilisation structures and events are essential for plant reproduction as they ensure the successful transfer of male gametes to the female gametes, leading to seed and fruit formation.
