✅ Answer Key + Detailed Solutions
1. Answer: B – Nawaschin
Explanation: S.G. Nawaschin discovered double fertilization in flowering plants.
2. Answer: B – 7-celled, 8-nucleate
Explanation: The typical Polygonum-type embryo sac consists of seven cells and eight nuclei.
3. Answer: C – Primary endosperm nucleus
Explanation: Triple fusion produces the primary endosperm nucleus, which develops into the endosperm.
4. Answer: C – Stigma
Explanation: The stigma receives compatible pollen grains during pollination.
5. Answer: B – Exine
Explanation: Exine is the tough outer wall of pollen grains made of sporopollenin.
6. Answer: B – Egg cell
Explanation: The egg cell fuses with one male gamete to form the zygote.
7. Answer: C – Xenogamy
Explanation: Xenogamy is pollination between flowers of different plants of the same species.
8. Answer: B – Endosperm
Explanation: Endosperm provides nourishment to the developing embryo.
9. Answer: C – Anther
Explanation: Microsporangia within the anther produce pollen grains.
10. Answer: B – Seed formation without fertilization
Explanation: Apomixis is asexual seed formation without fertilization.
