5. Heterospory occasionally occurs in lycophytes and ferns, and in all seed plants. Botanists are convinced that heterospory must have originated more than once in the evolution of plants. Can you suggest one or more advantages that heterospory might have to plants

An advantage to heterospory is endosporic gametophyte.

The endosporic gametophyte do permits for embryonic formation. It prompts it to have a reduced vulnerability to varying form of environments.

The second advantage that heterscopy could offer to plants is ensuring of a well apportioned nutrient filled environment.

The well apportioned nutrient filled environment is formed as a result of the megasporangium been adhered to the sporophytic plant body. This sees to promote a good formation of the embryo.

A further advantage of heterscopy is the aftermath of fertilization.

This integument is hard as it is necessary to preserve the female gametophyte and embryo.

true                                                                                                       true true true true true true

the answer is a) cell division.

hope this !
