Biology Question on sexual reproduction in flowering plants
In a flowering plant, archesporium gives rise to
A
Only the wall of the sporangium
B
Both wall and the sporogenous cells
C
Wall and the tapetum
D
Only tapetum and sporogenous cells
Answer
Both wall and the sporogenous cells
Explanation
Solution
In flowering plants, archaesporial cells are vertical rows of hypodermal cells at four angles of anther. These undergo periclinal (transverse) division to form an outer primary parietal cell and inner sporogenous cell. Primary parietal wall after few more periclinal divisions forms anther wall and sporogenous cells give rise to sporogenous tissue.
