Primary endosperm nucleus is formed by fusion of
1 Two polar nuclei and two male gametes
2 Two polar nuclei and one male gamete
3 Ovum and male gamete
4 One polar nucleus and male gamete
Explanation:
In gymnosperms primary endosperm nucleus is formed by the fusion of two haploid polar nuclei and one haploid male gamete (nuclei).

Arrange the following events in the correct sequence during the process of fertilization in Angiosperms
1 A -II B - III C - IV D - I E - II
2 A -I B - IV C - V D - II E - III
3 A -II B - V C - IV D - III E - I
4 A -V B - IV C - I D - II E - III
Explanation:
The correct sequence during the process of fertilization in Angiosperm is-Transfer of pollen grains form anther to stigma $\rightarrow$ pollen tube formation $\rightarrow$ Release of male gametes in to cytoplasm synergid $\rightarrow$ fusion of male gamete with egg nucleus $\rightarrow$ fusion of other male gamete with polar unclei.

Number of cells in the Angiosperm pollen grains at the time of release are-
1 2 cells
2 3 cells
3 1 cells
4 4 cells
Explanation:
: In the angiosperm pollen grains at the time of release have 2 cells. That is vegetative cell and generative cell. Pollen grains of Angiosperms are most simplified of all the seed plants. Male gametophyte or pollen grain produces three cells one vegetative cell which later forms pollen tube and two sperm cells. Inside the pollen are two cell that comprise the male gametophyte and the tube cell (also referred to as the tube nucleus) which develops into the pollen tube.
