Q

Alternation of Generations

A

members of a species exist in two body forms, one
sexual and one asexual. Alternation of generations is seen in some red and green algae
and all higher plants.

25
Q

What is a gametophyte

A

the haploid phase of a plant’s life cycle that produces gametes (sperm and eggs) for sexual reproduction

34
Q

Gametophyte generation

A

haploid (n) multicellular; makes haploid

35
Q

Sporophyte generation

A

diploid (2n) multicellular; grows from the zygote;
makes haploid (n) spores by meiosis that germinate into a new gametophyte.
