Biology 1407 Test 4

Question 1

bryophyte

Answer 1

member of an early-evolving plant lineage with a gametophyte dominant life cycle; a moss, liverwort, or hornwort

Question 2

embryophytes

Answer 2

land plants; clade of multicelled, photosynthetic species that protect and nourish the embryo on the parental body

Question 3

gametophyte

Answer 3

a haploid, multicelled body that produces games in the life cycle of land plants and some algae

Question 4

plants

Answer 4

lineage of multicelled, typically photosynthetic eukaryotes adapted to life on land

Question 5

seed plant

Answer 5

plant that produces seeds and pollen; an angiosperm or gymnosperm

Question 6

sporophyte

Answer 6

diploid, spore-producing body in the life cycle of land plants and some algae

Question 7

vascular plant

Answer 7

plan having specialized tissues (xylem and phloem) that transport water and sugar within the plant body

Question 8

cuticle

Answer 8

secreted covering at a body surface

Question 9

lignin

Answer 9

material that stiffens cell walls of vascular plants

Question 10

phloem

Answer 10

in vascular plants, tissue that distributes photosynthetically produced sugars through the plant body

Question 11

pollen grain

Answer 11

male gametophyte of a seed plant

Question 12

seed

Answer 12

embryo sporophyte of a seed plant packages with nutritive tissue inside a protective coat

Question 13

stomata

Answer 13

closable gaps defined by guard cells on plant surfaces; when open, they allow water vapor and gases to diffuse across the epidermis

Question 14

vascular tissue

Answer 14

in vascular plants, tissue (sylem and phloem) that distributes water and nutrients through the plant body

Question 15

xylem

Answer 15

in vascular plants, tissue that distributes water and dissolved minerals through the plant body

Question 16

gametangium

Answer 16

gamete-producing organ of a plant

Question 17

peat bog

Answer 17

high-latitude community dominated by sphagnum moss

Question 18

rhizoid

Answer 18

threadlike structure that anchors a bryophyte

Question 19

sporangium

Answer 19

of plants and fungi, a structure in which haploid spores form by meiosis

Question 20

epiphyte

Answer 20

plant that grows on another plant but does not harm it

Question 21

rhizome

Answer 21

stem that grows horizontally along or under the ground

Question 22

sorus

Answer 22

cluster of spore producing capsules on a fern leaf

Question 23

strobilus

Answer 23

of some nonflowering plants such as horsetails and cycads, a cluster of spore-producing structures

Question 24

coal

Answer 24

fossil fuel formed over millions of years by compaction and heating of plant remains

Question 25

megaspore

Answer 25

haploid spore formed in ovule of seed plants; develops into an egg-producing gametophyte
