Question 19

lineage of green algae that are closely related to land plants

Answer 19

charophytes

Question 20

Question 21

akfjkajdsfkjkf

Answer 21

liverworts

Question 22

sporophyte may be partially photosynthetic, cells have a single large chloroplast (as opposed to many)

Answer 22

hornworts

Question 23

gametophytes consist of small, leaf-like structures around a stem-like axis, anchored to substrate by rhizoids, tall, non-photosynthetic sporophyte stalks

Answer 23

mosses

Question 24

known as vascular plants, contain 2 types of vascular tissue, enable and enhance height and size

Answer 24

tracheophytes

Question 25

conducts water and dissolved minerals upward from the roots

Answer 25

xylem

Question 26

conducts sucrose and hormones throughout the plant

Answer 26

pholem

Question 27

what are the 3 major clades of tracheophytes?

Answer 27

(1) lycophytes
(2) pterophytes
(3) seed plants

Question 28

known as club mosses, the earliest vascular plants, lack seeds and no relation to true mosses, sporophyte dominant

Answer 28

lycophytes

Question 29

most belong to true ferns, the most abundant group of seedless vascular plants (11,000 species), much greater development in the life cycle, sporophytes have fronds (leaves), sporophyte generation is very large and separate from the gametophyte, sporophytes produce sori on the back of the fronds

Answer 29

pterophytes
