Answer 13

Gametes (Sperm and Egg)

Question 14

What do Sporophytes produce?

Answer 14

Spores

Question 15

What are the 3 groups of Bryophytes

Answer 15

1) Mosses
2) Liverworts
3) Hornworts

Question 16

How are bryophytes dispered?

Answer 16

Through the wind as they are very light

Question 17

Where are bryophytes mostly located

Answer 17

Moist forests and wetlands

Question 18

How can a moss retain it’s moisture?

Answer 18

They can go dormant during a drought and reactivate its cells when moisture becomes available

Question 19

What does the Sporophyte of a Moss consist of?

Answer 19

The foot, stalk, and sporangium

Question 20

Define the Sporangium

Answer 20

The site where meiosis and spore reproduction happen

Question 21

Answer 21

Long lived

Question 22

Are Liverworts Sporophytes long lived or short lived?

Answer 22

Short lived

Question 23

What is the most dominant phase of the Bryophyte cycle

Answer 23

Gametophyte

Question 24

How does the Gametophyte reproduce?

Answer 24

Sexually

Question 25

How does the Sporophyte reproduce?

Answer 25

Asexually

Question 26

Where is the Sporophyte located

Answer 26

Inside the female reproductive systejm of a plant

Question 27

Describe the 5 Steps of the Alternation of Generations for Bryophytes

Answer 27

1) The Gametophyte produces gametes
2) The egg and sperm form a zygote
3) The Sporophyte
4) Meiosis in Sporophyte produces a spores
5) Mitotic division of plant spore produces new gametophyte
