Question

In a young anther, the four rows of cells which later produce pollen are known as

• A. Antheridium
• B. Archesporium
• C. Tapetum
• D. Zoosporangium

Answer 1

Answer: (B)

Archesporium

Archesporium is the cell or group of cells from which spore mother cells develop. The archesporial cells form a primary parietal layer and a primary sporogenous layer. The parietal cells form a concentric wall of pollen sac. The cells of the primary sporogenous layer divide further and give rise to diploid sporogenous tissue which together forms pollen mother cell and undergoes meiosis and forms haploid spores.

So, the correct answer is option B.
