Answer 1

Explanation:

The development of the male gametophyte in angiosperms is called as micro gametogenesis. Pollen grain is the first cell of a male gametophyte. This cell undergoes only two divisions, with the result of first division two cells are formed - a large vegetative cell and a small generative cell. The second division is concerned with generative cell only. This division may take place either in pollen grain or in the pollen tube and gives rise to two male gametes. So, the correct answer is 'Generative cell'.
