9.8E). The antheridial cell divides to form the stalk cell and the spermatogenous
cell (body cell) in the pollen tube. The stalk cell forms a jacket around the
persistent prothallial cell (Fig. 9.8F, H). The spermatogenous cell gives rise to two
motile ...

Botany For Degree Gymnosperm (M.E.)
The multiple male cells developed from a single spermatogenous cell (or body
cell). The spermatogenous cell may assume a normal rounded or spherical
shape or it may become irregular in shape. It exhibited three types of
development in C.

From the latter, by a series of divisions, differentiate spermatogenous cell(s) and
a variable number of sterile jacket cells. In Isoetes and Azolla there. is one
spermatogenous cell producing four and eight sperms respectively; whereas in ...

In this way two jacket cells and one spermatogenous cell are formed. Due to
similar divisions in neighbouring cells two spermatogenous cells are surrounded
by four jacket cells. The jacket cells divide anticlinally to produce one- cell-thick ...

Botany For Degree Pteridophyta
A) from a single superficial cell that divides periclinally into an outer jacket initial
and inner spermatogenous cell. The nucleus of the spermatogenous cell
undergoes division and contains several free nuclei. Meanwhile the jacket initial
divides ...

Medaka: Biology, Management, and Experimental Protocols
The number of F1 generations that can be raised depends on the number of
spermatogenous cells of medaka and the frequency of the introduced mutation. If
there are only 50 spermatogenous cells in medaka, there is not much utility in ...

Further development takes place in the pollen chamber or the nucellar chamber
of the ovule after pollination. The generative cell divides to form a stalk cell (
Sterile cell) at the side of prothallial cell and a body cell (Spermatogenous cell).
