Plant tissue

2. Tubes: Slender, tubular cells with perforated walls in the phloem that transport food.
7. Region of active cell division.
9. Located at tips of roots and shoots, responsible for length.
12. Derived from embryonic tissue, forms permanent tissue.
14. Develops later in life (e.g. cork cambium)

1. A waxy, waterproof layer on the epidermis that prevents water loss.
3. Found at base of leaves or internodes (grasses).
4. Located on sides of roots and shoots, responsible for girth (vascular/cork cambium).
5. Earliest embryonic meristem.
6. Cells: Living phloem cells that regulate the metabolic activity of sieve tubes.
8. Vascular tissue responsible for the conduction of water and minerals upward from the roots.
10. Long, dead tubular cells in xylem with tapered ends that help transport water.
11. Tubular structures in xylem formed by cells placed end-to-end for efficient water conduction.
12. Vascular tissue that transports organic nutrients (food) from leaves to other parts of the plant.
13. Small pores in the epidermis surrounded by guard cells, allowing for gas exchange and transpiration
