What is the phenomenon called in which the length of the haploid and diploid phases vary among different groups in plants?
Options
- AAlternation of generation
- BMitosis
- CMeiosis
- DPlasmogamy
Correct answer
A. Alternation of generation
Step-by-step solution
Life cycle of plants has two distinct phases – the diploid sporophytic and the haploid gametophytic – that alternate with each other. The lengths of the haploid and diploid phases, and whether these phases are free– living or dependent on others, vary among different groups in plants. This phenomenon is called alternation of generation.
