Question 26

This Life Cycle is SPOROPHYTE dominant.

Answer 26

Fern Life Cycle

Question 27

This Life Cycle is Gametophyte dominant

Answer 27

Bryophyte Life Cycle

Question 28

SEQ Bryophyte Life Cycle starting from Fertilization

Answer 28

- Fertilization occurs, Diploid Zygote is formed inside of the Archegonium - Zygote becomes an Embryo - Embryo grows into a Mature Sporangium - Mature Sporangium produces spores -Spores become male (anthelida) and female (archaegonia) - Sperm produced in Anthelida fertilizes egg produced in Archaegonia -Process repeats

Question 29

SEQ Fern Life Cycle starting from Fertilization

Answer 29

- Fertilization occurs in Archaegonium, Diploid Zygote is formed -Zygote becomes embryo -Embryo grows into a Mature sporophyte containing sporangium - Sporangium produces spores - Spores grow into Hermaphroditic Gametophytes - Sperm fertilizes egg, process repeats

Question 30

What is a key difference between the Bryophyte and Fern Life Cycle?

Answer 30

- The Bryophyte life cycle contains two separate gametophytes (anthelida - male) and (archaegonia - female), while the Fern Life Cycle has Hermaphroditic Gametophytes - gametophytes contain both male and female structures [not individual]

Question 31

What is Hermaphroditic?

Answer 31

Containing both male and female structures Ex. Flowers [Plant Diversity 2]
