first organisms to grow in new or distrubed areas; break down rock and build soil
pioneer species
flowering vascular plants that produce a fruit containing one or more seeds; monocots and dicots
angiosperms
vascular tissue that produces xylem and phloem cells as a plant grows
cambium
pairs of cells that surround stomata and control their opening and closing
guard cells
threadlike structures that anchor nonvascular plants to the ground
rhizoids
plant w/ tubelike structures that move minerals water and other substances thru out the plant
vascular plant
vascular plants that do not flower, generally have needlelike or scalelike leaves, and produce seeds that are not protected by fruit conifers , cycads and ginkgoes
gymnosperm

stomata
chemical compound made out of sugar; forms tangled fibers in the cell walls or many plants and provide and support
cellulose
waxy protective layer that covers the stems leaves and flowers of many plants and helps prevent water loss
cuticle
angiosperm w/ one cotledon inside its seed, flower parts arranged in multiples of 3; and vascular tissue in bundles scattered thru out the stem
monocot
angiosperm w/ two cotyledons insdie its seed flower parts in multiples of 4-5 and vascular
dicot
