Across 4. the intermolecular attraction between like-molecules. 5. (2 wds) are small hair-like extensions of the outer layer of root CELLS 7. (2 wds) results ultimately from the evaporation of water from the surfaces of Cell s in the interior of the Leaves 10. is the process of converting light energy to chemical energy and storing it in the bonds of sugar 11. in plants, the outermost layer of cells covering the leaves and young parts of a plant 12. (2 wds) consists of xylem and phloem. These two types of vessels run side-by-side, extending from roots to leaves 13. (2 wds) consists of the epidermis and the periderm 15. (2 wds) which forms most of the bulk of a plant. Parenchyma are the least specialized. They have thin walls, numerous plastids including chloroplasts, and can revert to meristem in response to injury. 20. is the evaporation of water from the aerial parts of plants, especially leaves but also stems, flowers and roots 21. the tendency of certain dissimilar molecules to cling together due to attractive forces 22. (2 wds) is a part of the transport system in vascular plants. 23. (2 wds) includes organs such as leaves, buds, stems, flowers, and fruits and usually it develops above ground. 24. These are blister-like, lenticular breaks in the surface 25. (2 wds) in botany, part of the vascular system that conveys water and dissolved minerals from the roots to the rest of the plant and may also furnish mechanical support

Down 1. the contraction of cells within plants due to the loss of water through osmosis 2. are a protective waxy covering produced only by the epidermal cells 3. (2 wds) probably provide ATP, proteins, and other substances to the sieve-tube elements, whose cytoplasm lacks many structures necessary for cell maintenance. 5. (2 wds) osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves 6. (2 wds) is the set of the metabolic reactions and processes that take place in organisms' cells to convert biochemical energy from nutrients into adenosine triphosphate 8. is a tiny opening or pore, found mostly on the underside of a plant leaf and used for gas exchange 9. is usually just below the upper epidermis and is composed of regular layers of elongated cells 10. (2 wds) is usually found close to the other transport tissue in plants 14. are the cause of tip growth that is one of the most striking features of vegetative growth 16. (2 wds) control the stomatal openings in the epidermis of the leaf 17. force related to the stretching of an object 18. (2 wds) is the organ of a plant body that typically lies below the surface of the soil. 19. is a plant that has leaves and stems that die down at the end of the growing season to the soil level
