Back 6

is sensitive to change in moisture

is exemplified by the peristomal teeth in the sporophyte of mosses

may aid in spore dispersal in mosses

Front 7

Gemmae function for?

Back 7

Asexual reproduction

Front 8

sperm find their way to the archegonium

Back 8

by swimming

due to chemical gradient diffusing from the archegonium

as a result of sucrose being released during the breakdown of the neck canal cells of archegonium

Front 9

a protonema

Back 9

is the product of spore germination of a moss

flowering plants

Front 12

a tracheophyte is a plant that has

Back 12

xylem and phloem

Front 13

psilotum lacks

Back 13

roots

Front 14

Spore germination followed by cell division results in the production of

Back 14

a gametophyte

Front 15

what best describes a plant that is epiphyte

Back 15

A plant that grows upon another plant

Front 16

Club mosses

Back 16

are so called because most produce strobili

in ferns

Back 18

xylem and phloem are present in the sporophyte

the sporophyte is the dominant generation

develop a seed coat

Front 21

a pine tree is

Back 21

a sporophyte

diploid

Front 22

the male pine cone

Back 22

produces pollen

Front 23

the male gametophyte of a pine tree

Back 23

is produced within a pollen grain

produces sperm

which of these are produced directly by meiosis in pine

Back 24

microspores

Front 25

an ovule

Back 25

si the structure that develops into a seed

Front 26

the process by which pollen is transferred to the ovule is called

Back 26

pollination

Front 27

what is true of the female gametophyte of pine

Back 27

its a product of repeated cell divisions of the functional megaspore

its haploid

it serves as the stored food to be used by the embryo sporophyte upon germination
