new diploid individual

Question 17

Answer 17

in ALL plants

Question 18

dominant form is the one

Answer 18

typically present

Question 19

parasite form gets energy from

Answer 19

dominant form

Question 20

____ is dominant in nonvascular plants

Answer 20

gametophyte (n)

Question 21

____ is dominant in vascular plants

Answer 21

sporophyte (2n)

Question 22

nonvascular plants don’t have

Answer 22

vascular tissue (no xylem/phloem)

Question 23

nonvascular plants: water diffuses through

Answer 23

tissue (needs to live near water)

Question 24

nonvascular plants must be

Answer 24

small (water can’t be moved far without transpiration)

Question 25

example of nonvascular plants

Answer 25

moss, liverworts, hornworts

Question 26

moss lifecycle

Answer 26

*Gametophyte (n) is dominant form

*Sperm produced by male gametophyte swim to egg in female gametophyte

*Sporophyte (2n) is parasitic to the parent plant

Question 27

vascular seedless plants have

Answer 27

vascular tissue (has xylem/phloem)

Question 28

vascular seedless plants have ___ to strengthen cell walls

Answer 28

lignin

Question 29

___ can grow much taller than nonvascular plants

Answer 29

vascular seedless plants

Question 30

what is the dominant form of vascular seedless plants?

Answer 30

sporophyte (2n)

Question 31

vascular seedless plants formed huge forests during … period

Answer 31

carboniferous period

Question 32

example of vascular seedless plants

Answer 32

club/spike moss, ferns, horsetails

Question 33

fern lifecycle

Answer 33

• Sporophyte (2n) is dominant form
• Spores grow into smaller gametophytes on forest floor
• Sperm is produced by male gametophyte swim to egg in female gametophyte
  o They need water/most environment
• Both gametophyte and sporophyte survive on their own
