Question 21 • Fall 24 GSE Biology B-IC

In a plant’s life cycle, how many sporophyte generations occur between one gametophyte generation and the next time that eggs and sperm are produced?

Answer
A
zero
B
one
C
two
D
four

Explanation

A plant alternates between a gametophyte generation and a sporophyte generation. The gametophyte produces eggs and sperm; after fertilization, the resulting sporophyte produces spores, which grow into the next gametophyte. So one sporophyte generation occurs before eggs and sperm are produced again. The correct choice is “one.”
