Question

Gametophyte of Pteridophytes are

• A. Short lived, free living and sex organ bearing
• B. Heart shaped, dependent on sporophyte and sex organ bearing
• C. Fibre like, dependent on sporophyte and sex organ bearing
• D. Semi parasite on sporophyte

Answer 1

The correct option is A Short lived, free living and sex organ bearing

All Pteridophytes have a true alternation of generations, in which a dominant sporophyte generation produces spores through meosis, and a free-living gametophyte generation forms gametes (egg and sperm) by mitosis. The gametophyte produced by the germination of spore is thalloid and is often called as prothallus. It is monoecious i.e., bears both male (antheridia) and female (archegonia) sex organs. Hence the correct option is A.
