The diagram shows the life cycle of a fern. Which labels belong in the areas marked 1 and 3?

The life cycle of the fern has two different stages; sporophyte, which releases spores, and gametophyte, which releases gametes.

1-Sporophyte

3-Gametophyte

Explanation:

(in the life cycle of plants with alternating generations) the asexual and usually diploid phase, producing spores from which the gametophyte arises. It is the dominant form in vascular plants, e. g. the frond of a fern.
