The following question refers to the generalised life cycle for land plants shown in the figure. Each number within a circle or square represents a specific plant or plant part, and each number over an arrow represents meiosis, mitosis, or fertilisation.
- In the figure, which number represents the mature gametophyte?

Quizplus · Accepted Answer

In the generalised life cycle for land plants shown in the figure, number 7 represents the mature gametophyte. This is because after meiosis in the sporophyte, haploid spores are produced which divide mitotically to form the gametophyte. The gametophyte is the haploid stage in the life cycle, where gametes are produced. So, the mature gametophyte is represented by number 7 in the figure.
