How do female gameotophytes make their egg?

A

through mitosis

23
Q

Where is the egg in female gameotophytes made?

A

the archegonia

24
Q

What does the sperm need in order to travel to the female gameotophyte?

A

water

25
Q

What happens when the sperm reaches the female gameotophyte?

Q

What does the diploid zygote grow into?

A

a sporophyte

27
Q

What happens after the sporophyte is created?

the calyptra

29
Q

What does the capsule contain?
