Q. No.In a fertilised embryo sac, the haploid, diploid, and triploid structures are:
| 1. | Synergid, zygote, and primary endosperm nucleus |
| 2. | Synergid, antipodal and polar nuclei |
| 3. | Antipodal, synergid, and primary endosperm nucleus |
| 4. | Synergid, polar nuclei and zygote. |
Subtopic: Double Fertilization |

Level 1: 80%+
Hints
During double fertilisation in angiosperms:
| I: | One of the male gametes moves towards the egg cell and fuses with its nucleus thus completing the syngamy. |
| II: | The other male gamete moves towards the two polar nuclei located in the central cell thus completing the triple fusion. |
1. Only I is True
2. Only II is True
3. Both I and II are True
4. Both I and II are False
