Question:
Identify post fertilization events
Identify post fertilization events
Show Hint
Post-fertilization events in angiosperms include endosperm development, embryo formation, ovule maturation into seeds, and ovary transformation into fruit; events like syngamy occur during fertilization itself.

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding fertilization.
Fertilization in flowering plants involves the fusion of male gametes with female gametes. After fertilization, several developmental events occur which lead to seed and fruit formation.
Step 2: Post-fertilization events.
The key post-fertilization events include:
- Formation and development of endosperm from the second male gamete (part of double fertilization)
- Embryo development from the zygote (first male gamete + egg)
- Transformation of ovules into seeds as the embryo matures
- Development of ovary into fruit to enclose and protect seeds
Step 3: Exclude events that are pre-fertilization.
- Syngamy (fusion of male and female gametes) occurs during fertilization, so it is not post-fertilization.
- Double fertilization involves one male gamete fusing with egg and one with central cell; the act itself occurs during fertilization, not after.
Step 4: Conclusion.
Therefore, the post-fertilization events are: Development of endosperm, Embryo development, Ovules develop into seeds, Ovary develop into fruit.
