Question

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 1

Answer: (B)

Both wall and the sporogenous cells

In flowering plants, the archesporial cells (origin is hydrodermal) perform periclinal division to form two cells called the parietal cells and the sporogenous cells. The parietal cells develop many layers towards outer wall, while the sporogenous cells form a single layer towards inner side. Thus, archesporium gives rise to both wall and the sporogenous cells in flowering plants.

so, the correct answer is 'Both wall and the sporogenous cells'.
