Show Answer
Answer:
Correct Answer: B
Solution:
[b] In both the figures, the structure marked as 2 (in figure P) and C (in figure Q) are the male reproductive organs.
2 and 3 are respectively antheridium and testes sac.
An antheridium (or antheridia) is a haploid structure (or organ) producing and containing male gametes (called antherozoids or sperms).
It is present in the gametophyte phase of cryptogams like bryophytes and ferns, and also in the primitive vascular psilotophytes.
Testis sac is the pouch containing the testes and their accessory organs.
