Plant Life Cycles and Alternation of Generations
Question
Which one of the following shows diplontic life cycle?
Easy
Solution
In Fucus, the life cycle is diplontic as the haploid stage is limited to only gametes which are formed by gametic meiosis. Other stages are diploid. In brown alga Laminaria, bryophyte Marchantia and pteridophyte Lycopodium, the life cycles are haplo-diplontic in which both gametophyte and sporophytes have multicellular bodies.
