| stomata | tiny openings in a plant's epidermas through which carbon dioxide, water, and oxygen enter and exit |
| pioneer species | first organisms to grow in new or disturbed areas; break down rock and build up decaying plant material so that other plants can grow |
| phloem | vascular tissue that forms tubes that transport dissolved sugar throughout a plant |
| cellulose | chemical compound made out of sugar; forms of tangled fibers in the cell walls of many plants and provides structure and support |
| rhizoid | threadlike structures that anchor nonvascular plants to the ground |
| cambium | vascular tissue that produces xylem and phloem cells as a plant grows |
| vascular plant | plant with tubelike structures that move minerals, water, and other substances throughout the plant |
| nonvascular plant | plant that absorbs water and other substances directly through its cell walls instead of through tubelike structures |
| gymnosperm | vascular plants that don't flower, generally have needlelike or scale like leaves, and produce seeds that aren't protected by fruit; conifers, cyads,ginkgoes, and gnetophytes |
| dicot | angiosperm with two cotyledons inside its seed, flower parts in multiples of four or five, and vascular bundles in rings |
| guard cells | pars of cells that surround stomata and control their opening and closing |
| angiosperm | flowering vascular plants that produce fruits containing one or more seeds; monocots and dicots |
| monocot | angiosperm with one cotyledon inside its seed, flower parts in multiples of three, and vascular tissues in bundles scattered throughout the stem |
