A
a sporophyte grows from a spore
B
the gametes are produced by the gametophyte through meiosis and cellular differentiation
C
the spores are produced by the gametophyte by meiosis and cellular differentiation
D
the sporophyte is the haploid generation
E
the gametes are produced by the gametophyte through mitosis and cellular differentiation
Verified step by step guidance

Understand the concept of alternation of generations: In plants, this refers to the life cycle that alternates between two distinct forms, the sporophyte and the gametophyte.
Identify the characteristics of the sporophyte generation: The sporophyte is the diploid generation that arises from the fertilization of gametes. It produces spores through meiosis.
Identify the characteristics of the gametophyte generation: The gametophyte is the haploid generation that arises from spores. It produces gametes through mitosis and cellular differentiation.
Clarify the process of gamete production: In the gametophyte generation, gametes are produced by mitosis, not meiosis, because the gametophyte is already haploid.
Review the options given in the problem: The correct statement is that gametes are produced by the gametophyte through mitosis and cellular differentiation, aligning with the characteristics of the gametophyte generation.
