Elan Coil [88]

The true statement about the relationship between true moss sporophytes and gametophytes is: (d) Sporophytes are parasites of gametophytes.

Parasites are the organisms that live inside or outside an organism and depend upon that organism for their food as well. Apart from extracting food, the parasites also provide some kind of harm to the host they live in. Sporophytes are called parasites because they directly developed from the fertilized egg in archegonia.

Considering that the mature sporophytes of true mosses get their nutrition from the gametophytes on which they grow, and considering these generations as individual plants, what is true of the relationship between true moss sporophytes and gametophytes?

b. Sporophytes are mutualists of gametophytes.

c. Sporophytes are commensalist of gametophytes.
