Plant Kingdom

Given below are the stages in the life cycle of pteridophytes. Arrange the following stages in the correct sequence.

A. Prothallus stage

B. Meiosis in spore mother cells

C. Fertilisation

D. Formation of archegonia and antheridia in the gametophyte

E. Transfer of antherozoids to the archegonia in the presence of water

Choose the correct answer from the options given below:

  1. A.B, A, D, E, C✓
  2. B.B, A, E, C, D
  3. C.D, E, C, A, B
  4. D.E, D, C, B, A

Solution

Spore mother cells undergo meiosis to make spores (B); spores germinate into the prothallus (A); it forms antheridia and archegonia (D); antherozoids swim to the archegonia in water (E); fertilisation follows (C). So B, A, D, E, C.
