Answer:
E) In both mosses and ferns, moisture is required for sperm to reach the egg. In mosses, gametophyte is the dominant stage of the life cycle. In ferns, the sporophyte is the dominant stage of the life cycle.
Explanation:
The *sporophyte of fern plant is dominant over the smaller and nutritionally independent gametophyte*. The sporophytes are photosynthetic, long-lived and highly branched. *Sperm cells of fern possess whip-like flagella in their cell walls that enable moisture swim to reach the egg*
*In Mosses,the gametophyte is more prominent (dominant)* just like in lower plants. These organisms *require external water(moisture) in the form of dew or rain to move their sperm during fertilization*.
Therefore, *In ferns, the sporophyte is dominant over the gametophyte*, while *in mosses,gamatophyte is dominant over the sporophyte.* Both require moisture for sperm to reach egg.
