Answer 22

fungus

Question 23

merizein

Answer 23

to divide

Question 24

are ferns sporophyte or gametophyte dominant

Answer 24

sporophyte - seedless vascular

repeated cell division which sustains growth

Question 26

2 types of meristematic tissues

Answer 26

shoot apical root apical

Question 27

cuticle

Answer 27

waxy covering of epidermis - keeps water from evaporating

Question 28

stomata

Answer 28

specialized cells that allow for gas exchange between air/plant - surrounded by guard cells

Question 29

mycorrhizae

Answer 29

fungus/plant (root) interactions - bacteria and fungi needed for nutrients

2 types of mesophyll

Answer 30

palisade and spongy parenchyma

Question 31

xylem

Answer 31

transports water up tree

Question 32

phloem

Answer 32

bidirectional, photosynthetic products transported where needed

Question 33

nonvascular (bryophytes) phylums

Answer 33

- hepatophyta - liverwort - bryophyta - mosses - anthocerophyta - hornworts

Question 34

monile

Answer 34

necklace

Question 35

conifer

Answer 35

cone bearing

Question 36

Magnolia

Answer 36

French botanist

Question 37

vascular seedless phylum

Answer 37

- lycopodiophyta - lycophytes (club mosses, spike mosses, quillworts) - monilophyta - ferns, horsetails, whisk ferns

Question 38

seed vascular phylum

Answer 38

- coniferophyta - gymnosperms - magnioliophyta - angiosperms

Question 39

dominant generation in nonvascular plants

Answer 39

gametophyte

Question 40

vascular tissue

Answer 40

cells joined into tubes for transport of water and nutrients

Question 41

clades

Answer 41

groupings of common structure from common ancestor - from vascular plants

Question 42

grade

Answer 42

grouped together by key features, no common ancestry

Question 43

seed

Answer 43

embryo and nutrients surrounded by protective coat - seed plants form clade that can be further divided into more clades

Question 44

gymnosperms

Answer 44

seeds no enclosed in chambers

Question 45

angiosperms

Answer 45

seeds develop inside chambers that originate within flowers

Question 46

fruit =

Answer 46

ovary (receptacle)

Question 47

endosperm

Answer 47

- food for developing embryo - triploid - created by double fertilization

Question 48

cotyledon

Answer 48

"seed-leaf"

Question 49

dominant generation in vascular plants

Answer 49

sporophyte

Question 50

vascular plant characteristics

Answer 50

- sporophyte dom gen - well-developed roots/leaves - xylem and phloem - sporangium

Question 51

sporangium

Answer 51

vessel-containing spores - produces spores

Question 52

xylem

Answer 52

- conducts most of water and minerals - includes tube-shaped cells called tracheids - water-conducting cells strengthened by lignin and provide

Question 53

phloem

Answer 53

- cells arranged in tubes that distribute sugars, amino acids, and organic products

Question 54

what allows for increased height

Answer 54

vascular tissues

Question 55

roots

Answer 55

organs that anchor vascular plants - enable absorption of water, nutrients, and oxygen for soil

Question 56

leaves

Answer 56

organs that increase surface area of vascular plants to capture more solar energy for photosynthesis
