Question

In a flowering plant, archesporium gives rise to

(a) only tapetum and sporogenous cells 

(b) only the wall of the sporangium 

(c) both wall and the sporogenous cells 

(d) wall and the tapetum

Answer 1

Correct option (c) both wall and the sporogenous cells 

Explanation

The archesporial cells divide periclinally, cutting off primary parietal layer (forming wall later on) towards the outer side and primary sporogenous cells towards the inner side. The cells of the primary parietal laves divide by successive perietal and anticlinal division to form concentric layers of pollen sac wall.
