1. The diagram shows the life cycle of a moss.

(a) Mark the diagram with a cross to show where meiosis occurs.

(b)  A spore of this organism contains 16 chromosomes. How many chromosomes would you expect to find in:


a female gamete
  • 16


a cell taken from the the moss during the diploid stage of its life cycle?
  • 32
(c) Suggest two ways in which the male gametes of this organism are likely to differ from female gametes.

  • more numerous
  • motile
  • female gametes would have greater food store
