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.
