Question

In pteridophytes prothallus produces-

• A. Sporangia
• B. Antheridia and archegonia
• C. Vascular tissues
• D. Root, stem and leaf

Answer 1

The correct option is B Antheridia and archegonia

• The free-living, multicellular and photosynthetic gametophytes of pteridophytes are called as the prothallus.
• Pteridophytes show alternation of generations. The dominant sporophyte produces spores through meiosis. The gametophyte generation forms gametes by mitosis. The spores are produced by the sporangia in the spore mother cells. These spores germinate and give rise to gametophytes.
• The gametophytes (prothallus) produces the male sex organs called antheridia and female sex organs called archegonia.
• So the correct option is B.
