The Life Cycles of Plants

Question 6 • AFC Biology B S3

What do the moss life cycle and the fern life cycle have in common?

Answer
A
Double fertilization produces a 3n cell.
B
Seeds are protected and nourished by a fruit.
C
The zygote is the first cell of the gametophyte phase.
D
Fertilization produces a diploid cell.

Explanation

In both mosses and ferns, fertilization occurs when a haploid sperm joins a haploid egg. Their chromosome sets combine to form a diploid zygote, so “Fertilization produces a diploid cell” is the common feature. Double fertilization and fruit-protected seeds are traits of flowering plants, not mosses or ferns.
