In mosses, which generation is dominant and what is its ploidy level?
Answer
The gametophyte generation is dominant and it is haploid.
The correct answer is The gametophyte generation is dominant and it is haploid. — State the dominant generation and its ploidy.
Step-by-step solution
- Recall that mosses are non‑vascular plants with alternation of generations.
- Identify the visible, long‑lived part of the plant.
- The green, photosynthetic plant body is the gametophyte.
- Since gametophytes arise from spores, they contain a single set of chromosomes, i.e., they are haploid.
- State the dominant generation and its ploidy.
Common mistake: Confusing the sporophyte as the dominant generation.
