Question

Vascular plants exhibit alternation of generation. What is alternation of generation?

Answer 1

The correct answer to this question is this one: "C. The plant exists as a diploid organism, and at other times as a haploid." Vascular plants exhibit alternation of generation. The alternation of generation is presented as the plant exists as a diploid organism, and at other times as a haploid.

Answer 2

Answer;

C. The plant exists as a diploid organism, and at other times as a haploid.

Explanation;

• Alteration of generation occurs when vascular plants undergo a life cycle that takes them through both haploid and diploid generations. The generations involved are the gametophyte generation which the haploid generation and the sporophyte generation which is diploid.
• Gametophyte generation begins with spores which are haploids and are produced by meiosis. Cells derived from the spores are also haploid due to mitosis process. Gametes produced from the spores undergo sexual reproduction producing diploid sporophyte generation.
• Sporophyte generation begins with a zygote which has diploid cell, which will then undergo meiosis and form spores which are diploid and eventually start the gametophyte generation.
