Vedclass · Answer

(A) In Selaginella,the male gametophyte development begins within the microspore while it is still inside the microsporangium.The mature $13$-celled male gametophyte consists of:$1$ prothallial cell (which is the first cell formed).$4$ jacket cells (which form the outer layer of the antheridium).$8$ androgonial cells (which eventually produce the spermatozoids).Thus,the total number of cells is $1 + 4 + 8 = 13$ cells.This corresponds to $1$ prothallial cell and $12$ antheridial cells ($4$ jacket $+ 8$ androgonial cells).
