In Funaria, calyptra is formed from

examples of bryophytes plant kingdom biology

  1. Capsule

  2. Archegonium

  3. Columella

  4. Antheridium

Show answer
Correct Option: B
Explanation:

  • In the majority of bryophytes, embryonic sporophytes elongate gradually to form a foot and a spore-bearing capsule. Calyptra is an enlarged archegonial venter in bryophyte that protects the capsule containing the embryonic sporophyte.
  • Columella is a column of sterile tissues which extends through the theca and are surrounded by spore-producing cells. Antheridium is the male sex organ of algae, fungi, ferns, and other nonflowering plants
So the correct answer is B.
