Question | Answer |
Pairs of cells that surround stomata and control their opening and closing | Guard Cells |
Chemical compound made out of sugar; forms tangled fibers in the cell walls of many plants and provides structure and support | Cellulose |
Plant with tube-like structures that move minerals, water, and other substances throughout the plant | Vascular Plant |
Waxy, protective layer that covers the stems, leaves, and flowers of many plants and helps prevent water loss | Cuticle |
Angiosperm with one cotyledon inside its seed, flower parts in multiples of three, and vascular tissues in bundles scattered throughout the stem | Monocot |
Threadlike structures that anchor nonvascular plants to the ground. | Rhizoid |
First organisms to grow in new or disturbed areas; break down rock and build up decaying plant material so that other plants can grow | Pioneer Species |
Plant the absorbs water and other substances directly through its cell walls instead of through tube-like structures | Nonvascular Plant |
Flowering vascular plants that produce fruits containing one or more seeds; monocots and dicots | Angiosperm |
Tiny openings in a plant’s epidermis through which carbon dioxide, water vapor, and oxygen enter and exit | Stomata |
Vascular tissue that forms hollow vessels that transport substances, other than sugar (like water), throughout a plant | Xylem |
Vascular tissue that forms tubes that transport dissolved sugar (food) throughout a plant | Phloem |
Vascular tissue that produces xylem and phloem cells as a plant grows | Cambium |
Angiosperm with two cotyledons inside its seed, flower parts in multiples of four or five, and vascular bundles in rings | Dicot |
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 | Gymnosperm |
