2. __________ system is the plant organ system that includes all tissues located below ground.
5. Waxy, non-cellular, waterproof coating that covers a plant's leaves and stems.
6. Root __________ is an extension of a specialized dermal cell on a plant root, which absorbs water and minerals.
10. __________ cells are a type of small phloem cells adjacent to sieve tube cells that appear to control sugar transport in phloem.
12. __________ tissue is vascular tissue that transports carbohydrates and water from the leaves to other parts of the plant.
14. __________ tissue is the outermost cell layer of plants; also called epidermis.
15. __________ cell is specialized epidermal cell that swells and contracts to control gas exchange through a stoma in a leaf.
16. Enlarged underground stem that stores food.

1. __________ system is the plant organ system that includes all tissues located above ground.
3. Describes a soft plant stem with little or no woody tissue.
4. __________ tissue is the transport tissue formed of cells joined into tubes that carry water and nutrients through the body of the plant.
7. __________ tissue are parts of the plant body not included in the other 2 tissue systems; function in storage, photosynthesis, and support.
8. Pores that allow gases to pass through the epidermis of a leaf.
9. __________ tissue is vascular tissue that conducts water and minerals from the roots to the leaves in plants.
11. Growth region of the plant with tissue in which cells divide by mitosis.
13. __________ tube is formed by a stack of sieve tube cells to allow conduction of phloem in plants.
