Options

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

C

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 layes divide by successive periclinal and anticlinal division to form concentric layers of pollen sac wall.
