Plant tissue

3. Bean-shaped sclerenchyma cells in the epidermis; swell and shrink by osmosis to open and close stomata. Stomata (singular stoma) are tiny pores in the epidermis of a plant leaf that controls transpiration and gas exchange with the air.
6. The primary tissue of higher plants composed to thinwalled cells that remain capable of cell division even when mature, constitutes the greater part of leaves, roots, the pulp of fruits, and the pith of stems.
7. A portion of ground tissue that is the inner most layer of a cortex and has a casparian strip in its anticlinal cell walls.
8. Tissue composed of cells with unevenly thickened walls.
9. Long tubular cell peculiar to xylem
13. Tissue composed of thick-walled cells containing lignin for strength and support

1. In animals, outer layer of skin that consists mainly of epithelial cells and lacks nerve endings and blood vessels; in plants, outer layer of dermal tissue.
2. Tissue that conducts water and nutrients through the plant body
4. Waxy, waterproof substance produced by epidermal cells of leaves, shoots, and other above-ground parts of plants; prevents damage and loss of water by evaporationModifications of new cells to form tissues or organs with a specific function.
5. A series of sieve-tube elements arranged end to end and interconnected through sieve plates.
10. Epidermal cell extensions of young root that increase absorptive surface area
11. Undifferentiated tissue from which new cells are formed, as at the tip of a stem or root.
12. is vascular tissue that transports food (sugar dissolved in water) from photosynthetic cells to other parts of the plant for growth or storage. This type of tissue consists of living cells that are separated by end walls with tiny perforations, or holes.
