Q. The 13-celled male gametophyte in $Selaginella$ is
A) 12 cells of antheridium + 1 prothallial cell
B) 10 cells of antheridium + 3 prothallial cells
C) 8 cells of antheridium + 2 prothallial cells
D) None of the above
Explanation
The 13-celled microspore of male gametophyte in $Selaginella$ is sheded from microsporagium, which is having 1-prothallial cell + 8-jacket cells +4-androgonial cells (i.e., 8+4=12 antheridial cells).
