Question

Why sporophytes are parasitic over gametophyte in bryophytes?

Answer 1

Answer:

The World of Biology Website states "In Seed Plants, the Gametophyte is a very small Parasite of the Sporophyte." "The young sporophyte, as for ferns, develops initially as a parasite on the gametophyte." ... Clearly the concept of a plant being parasitic on its other generation is not unique to bryophytes.

Answer 2

Explanation:

In higher plants like ferns and fern allies, the sporophyte stage is dominant. Gametophytes produce gametes (sperm and eggs) in a special structure called a gametangium (-ia), while sporophytes produce spores in a special structure called a sporangium (-ia). Second, all plants need to get water to their cells.
