1. | Synergids, antipodals and Polar nuclei |
2. | Synergids, Primary endosperm nucleus and zygote |
3. | Antipodals, synergids, and primary endosperm nucleus |
4. | Synergids, Zygote and Primary endosperm nucleus |
What is the fate of the male gametes discharged in the synergid?
1. | One fuses with the egg and the other fuses with central cell nuclei |
2. | One fuses with the egg and the other(s) degenerate(s) in the synergid |
3. | All fuse with the egg |
4. | One fuses with the egg and the other(s) fuse(s) with a synergid nucleus |
1. | Fusion of two male gametes of a pollen tube with two different eggs |
2. | Fusion of one male gamete with two polar nuclei |
3. | Fusion of two male gametes with one egg |
4. | Syngamy and triple fusion |
Double fertilization is exhibited by:
1. Algae
2. Fungi
3. Angiosperms
4. Gymnosperms
Endosperm is formed during double fertilization by:
1. Two polar nuclei & one male gamete
2. One polar nucleus & one male gamete
3. Ovum and male gamete
4. Two polar nuclei & two male gametes
