Question

What happens to motile spore after it ejects from sporophytes in pteridophyte plants?

• A. It germinates to become another spore forming a fern plant
• B. It germinates to become a prothallus
• C. It joins with another spore to become a seedling
• D. It encysts and devours by snail-like organisms

Answer 1

The correct option is B It germinates to become a prothallus

Pteridophytes are seedless ferns. They use sexual and asexual mode of reproduction. Spores produced by pteridophytes that help in sexual reproduction. These spores are carried long distances for pollination by abiotic factors like wind, water, etc. Once the spore reaches its destination, it releases the male gametes into the female reproductive system and merges with the female gamete. After successful divisions, it germinates to become prothallus, i.e, the young ones of pteridophytes. So, the correct answer is option B.
