Chapter 23-25

Front 1

the waxy, waterproof layer that covers the surface of most plants (they help prevent the plant from drying out by reducing the evaporation of water from leaves and stems.)

Back 1

Cuticle

Front 2

tiny pores through which carbon dioxide enters a leaf and water and oxygen exit; they can open or close to regulate water loss

Back 2

Stomata

Front 3

grains are tiny male gametophytes that can be carried by insects or the wind

Back 3

Pollen

Front 4

a system of internal interconnecting tubes that transport water and other nutrients throughout the plant

Back 4

Vascular System

Front 5

plants with vascular tissue

Back 5

Vascular Plants

Front 6

plants, such as mosses, that do not have vascular tissue

Back 6

Nonvascular Plants

Front 7

a structure that contains the embryo of a plant

Back 7

Seed

Front 8

vascular plants that produce seeds

Back 8

Seed Plants

Front 9

reproductive structure that produces pollen and seeds

Back 9

Flower

Front 10

gametes are produced by a haploid for of the plant called...

Back 10

Gametophyte

Front 11

when two gametes join during fertilization, they form the diploid for of the plant called...

Back 11

Sporophyte

Front 12

the cycle of alternating haploid and diploid generations

Back 12

Alternation of Generations

Front 13

the vascular tissue (tubes) through which water and minerals travel

Back 13

Xylem

Front 14

vascular tissue through which sugars and other organic molecules travel

Back 14

Phloem

Front 15

aboveground part of a plant

Back 15

Shoot

Front 16

part of the body that grows downward

Back 16

Root

Front 17

region of actively dividing plant cells where plant growth occurs

Back 17

Meristems

Front 18

have rootlike structures; they anchor the gametophytes to the surfaces on which they grow

Back 18

Rhizoids

Front 19

are plants with seeds that don't develop within a fruit

Back 19

Gymnosperms

Front 20

plants that have flowers

Back 20

Angiosperms

Front 21

an enlarged ovary of a flowering plant

Back 21

Fruit

Front 22

the transfer of pollen grains from the male reproductive structures of a plant to the female reproductive structures

Back 22

Pollination

Front 23

a male gametophyte of a seed plant develops into

Back 23

Pollen grain

Front 24

the female gametophyte develops inside

Back 24

Ovule

Front 25

once the pollen grain reaches a compatible female reproductive structure the pollen tube grows out of the pollen grain down to the ovule so that the sperm can pass directly to the egg

Back 25

Ovule

Front 26

the male part of a flower that produces pollen

Back 26

Steamen

Front 27

top part of the stamen where pollen is produced

Back 27

Anther

Front 28

female part of a flower

Back 28

Pistil

Front 29

base of the pistil where eggs are produces

Back 29

Ovary

Front 30

eggs are produced within..

Back 30

Ovules

Front 31

sticky tip of the pistil where pollen would be deposited for fertilization

Back 31

Stigma

Front 32

a layer of flattened cells that cover a plant's body

Back 32

Epidermis

Front 33

tiny projections that grow from the area just above the root cap

Back 33

Root Hairs

Front 34

cluster of cells that covers and protects the tip of a root

Back 34

Root Cap

Front 35

loss of water vapor through the stomata of a plants leaves

Back 35

Transpiration

Front 36

transport of nutrients within phloem tissue

Back 36

Translocation
