Front 1

waxy, protective layer that covers the stems, leaves, and flowers of many plants and helps prevent water loss

Back 1

cuticle

Front 2

chemical compound made out of sugar; forms tangled fibers in the cell walls of many plants and provides structure and support

Back 2

cellulose

Front 3

plant with tubelike structures that move minerals, water, and other substances throughout the plant

Back 3

vascular plant

Front 4

plant that absorbs water and other substances directly through its cell walls instead of through tubelike structures

Back 4

nonvascular plant

Front 5

threadlike structures that anchor nonvascular plants to the ground

Back 5

rhizoid

Front 6

first organisms to grow in new or disturbed areas; breakdown rock and build up decaying plant material so that other plants can grow

Back 6

pioneer species

Front 7

small openings in the surface of most plant leaves that allow carbon dioxide, water, and oxygen to enter and exit

Back 7

stomata

Front 8

pairs of cells that surround stomata and control their opening and closing

Back 8

guard cells

Front 9

vascular tissue that forms hollow vessels that transport substances, other than sugar, throughout a plant

Back 9

xylem

Front 10

vascular tissue that forms tubes that transport dissolved sugar throughout a plant

Back 10

phloem

Front 11

vascular tissue that produces xylem and phloem cells as a plant grows

Back 11

cambium

Front 12

vascular plants that do not flower, generally have needlelike or scalelike leaves, and produce seeds that are not protected by fruit; conifers, cycads, ginkgoes, and gnetophytes

Back 12

Front 14

angiosperm with one cotyledon inside its seed, flower parts arranged in multiples of three, and vascular tissues in bundles scattered throughout the stem

Back 14

monocot

Front 15

angiosperm with two cotyledons inside its seed, flower parts in multiples of four or five, and vascular bundles in rings

Back 15

dicot
