Question:medium

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 gametophyte
E. Transfer of antherozoids to the archegonia in presence of water Choose the correct answer from the options given below:

Show Hint

In pteridophytes, water is essential for the transfer of antherozoids (sperm) to the archegonia (egg), which is a key step in fertilisation.

  • B, A, E, C, D
  • D, E, C, A, B
  • E, D, C, B, A
  • B, A, D, E, C
Hide Solution

The Correct Option is D

Solution and Explanation

The pteridophyte life cycle proceeds as follows: B. Meiosis within spore mother cells generates spores. A. Spores germinate, initiating the prothallus stage. D. The prothallus matures to develop archegonia and antheridia, the reproductive structures. E. Antherozoids are transported to the archegonia via water, facilitating fertilization. C. Fertilization takes place, leading to the formation of a zygote. The correct sequence is B, A, D, E, C.
