Verified
Which generation is significantly reduced in size and entirely dependent on the sporophyte generation?
A) Megasporangium
B) Gymnosperms
C) Gametophyte
D) Angiosperms
E) Integuments
Sporophyte Generation
The stage in the life cycle of plants and algae where the organism is diploid and generates spores.
Gametophyte
The haploid stage in the life cycle of plants and algae that produces gametes through mitosis for sexual reproduction.
Megasporangium
In a heterosporous plant, structure in which megaspores are produced. Megasporangia of seed plants are ovules that develop into seeds following fertilization. Compare with microsporangium.

Final Answer :
C
Explanation :
The gametophyte generation is significantly reduced in size and entirely dependent on the sporophyte generation in both gymnosperms and angiosperms. This is a characteristic feature of the life cycles of these plants, where the sporophyte is the dominant, photosynthetically active phase, and the gametophyte is often microscopic and lives attached to or within the tissues of the sporophyte.
