Cell and Tissue Types

3. Region of constantly dividing cells.
4. Short and fat sclerenchyma cells.
5. An elongated, thick-walled conducting and supporting cell of xylem. It has tapering ends and pitted walls without perforations.
6. The main organs of photosynthesis and transpiration.
10. Tiny openings or pores in plant tissue that allow for gas exchange.
12. Important in photosynthesis, storage, or secretion. Thin primary wall, LAM, and no lignin. Often in pith or cortex.
15. Cells provide support and mechanical protection. Often DAM as they are heavily lignified.

1. Long and skinny sclerenchyma cells.
2. Cells that begin to specialize.
4. The main body or stalk of a plant or shrub, typically rising above ground but occasionally subterranean.
7. Stem and leaves.
8. Complex food conducting tissue.
9. Cell in tissue with abundant air space and low number of chloroplast.
11. Support is its primary function. It has a lot of pectin and hemicellulose in irregularly thickened primary cell walls.
13. The part of a plant which attaches it to the ground or to a support, typically underground, conveying water and nourishment to the plant.
14. Cells that are actively dividing.
