Across
- 6. The living system of interconnected protoplasts extending through a plant, used as a transport pathway for the movement of water and solutes
- 7. A plant adapted to survive in conditions where water is in short supply
- 8. A pore in the epidermis of a leaf, bounded by two guard cells and needed for efficient gas exchange
- 10. A dead, empty tube with lignified walls, through which water is transported in plants, formed by xylem vessel elements lined up end to end
- 11. A strand of vascular tissue running longitudinally in a plant
- 12. A later covering, and secreted by, the epidermis, in plants, it's made of a fatty substance called cutin
- 14. The region of a leaf between the upper and lower epidermis
- 16. plants which seeds contain an embryo with two cotyledons in their seeds
- 17. A basic plant tissue typically used as packing tissue between more specialized structures, it's metabolically active and may have a variety of functions such as food storage and support
- 19. A tissue in plants consisting mainly of xylem and phloem but also containing sclerenchyma and parenchyma cells
- 22. A cell with unthickened cellulose walls and dense cytoplasm that in found in close association with a phloem sieve tube element to which it is directly linked via many plasmodesmata
- 23. A plant tissue consisting of thick-walled cells with a purely mechanical function, many of these cells take the form of fibers
- 24. The layer of cells surrounding the vascular tissue of plants
- 25. The outer layer of cells covering the body of a plant or animal, in plants usually one cell thick and may be covered with a cuticle
- 28. Very small, accurately drawn scale of known dimensions, engraved on a microscope slide
Down
- 1. A cell found in phloem tissue, with non-thickened cellulose walls, very little cytoplasm, no nucleus, and end walls perforated to form sieve plates
- 2. A site in a plant which provides food for another part of the plant, the sink
- 3. A site in a plant which receives food from another part of the plant, the source
- 4. The loss of water vapor from a plant to its environment, mostly taking place through the stomata in the leaves
- 5. A dead, lignified cell found in xylem specialized for transporting water and for support
- 9. A term referring to tubes or vessels
- 13. The non-living system of interconnected cell walls extending throughout a plant, used as a transport pathway for the movement of water and mineral ions
- 15. A modified form of parenchyma in which the corners of the cells have extra cellulose thickening, providing extra support
- 17. A tissue containing tubes called sieve tubes and other types of cell, responsible for the transport through the plant of organic solutes
- 18. A system of fluid-filled tubes, vessels or spaces, most commonly used for long-distance transport in living organisms
- 20. Small scale that is placed in a microscope eyepiece
- 21. A tissue containing tubes called vessels and other types of cell, responsible for the transport of water and mineral salts through a plant and for support
- 26. Tube formed from sieve tube elements lined up end to end
- 27. A hard material made by plants and used to strengthen the cells walls of certain types of cell
