Question

Arrange the following events in the correct sequence during the process of fertilization in Angiosperms: I. Fusion of other male gamete with polar nuclei
II. Transfer of pollen grains from anther to stigma
III. Fusion of male gamete with egg nucleus
IV. Release of male gametes into cytoplasm synergid
V. Pollen tube formation

• A. I III V II IV
• B. I IV V III II
• C. II IV V I III
• D. IV II III V I

Hint:

Fertilization in Angiosperms involves complex processes such as pollen tube formation, fusion with the egg, and the formation of endosperm, which are essential for seed development.

Answer 1

The Correct Option is C

The correct sequence of events during the fertilization process in Angiosperms is: 1. II. Transfer of pollen grains from anther to stigma - The pollen grain is transferred from the anther to the stigma.
2. IV. Release of male gametes into cytoplasm of synergid - The male gametes are released into the synergid cells of the ovule.
3. V. Pollen tube formation - The pollen tube forms to allow the male gametes to travel down to the egg.
4. I. Fusion of other male gamete with polar nuclei - One of the male gametes fuses with the polar nuclei to form the triploid endosperm.
5. III. Fusion of male gamete with egg nucleus - Finally, the second male gamete fuses with the egg nucleus to form the zygote.
Thus, the correct order is "II IV V I III."
