Multiple choice examples of bryophytes plant kingdom biology

The gametophyte of Funaria is

  1. Dioecious and autoicous

  2. Monoecious and autoicous

  3. Monoecious and heteroicous

  4. Dioecious and heteroicous
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Funaria is monoecious (both sex organs on the same plant) and autoicous (sex organs on different branches of the same plant).

Multiple choice examples of bryophytes plant kingdom biology

In Funaria, calyptra is formed from

  1. Capsule

  2. Archegonium

  3. Columella

  4. Antheridium
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

Chloroplasts are found in the spores of

  1. Yeast

  2. Funaria

  3. Dryopteris

  4. Rhizopus
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Funaria spores contain chloroplasts, which allow them to begin photosynthesis immediately upon germination.

Multiple choice examples of bryophytes plant kingdom biology

In life cycle of Funaria spores are beginning of the generation

  1. Gametophytic

  2. Sporophytic

  3. Both A and B

  4. Peristome
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Spores are the first cells of the gametophytic generation in the moss life cycle, as they are haploid and germinate to form the protonema.
