Question

Total number of meiosis that occur in the sporangium of Nephrolepis is

• A. 1
• B. 4
• C. 16
• D. None of the above

Answer 1

Answer: (A)

1

Sporangium of Nephrolepis consists of 16 spore mother cells, which undergo meiosis only once to form haploid cells. The sporangia produce haploid meiospores. As the sporangia mature, the indusium shrivels, so that spore release is unimpeded. The sporangia then burst and release the spores.

So, the correct answer is option A.
