  1. Zygote formation

  2. Spore formation

  3. Bud formation

  4. Fragment formation

A Correct answer
Explanation

Asexual mode of reproduction refers to the involvement of one parent only. There are various modes of asexual reproduction like budding, fragmentation, fission, spore formation, etc. Zygote formation takes place only when two parents are involved. Thus, it is not an asexual mode of reproduction.

Multiple choice

  1. A mode of reproduction in which a limited number of colonial algae produce daughter colonies through replication.

  2. It is a process in which any cell of an organism produces one or more reproductive cells inside its cell wall.

  3. It is a method of reproduction through spore formation.

D Correct answer
Explanation

Gametophytic phase is the dominant and independent phase in the life cycle of algae. It is usually photosynthetic.

Multiple choice

The life cycle in Dryopteris is

  1. heteromorphic

  2. homomorphic

A Correct answer
Explanation

All pteridophytes exhibit a diplohaplontic heteromorphic life cycle in which both sporophytes and gametophytes are independent, free living and photosynthetic, but they are very much different in morphology and size. Dryopteris is a pteridophyte.
