Across
- 2. Cell Specialized cells in the epidermis of leaves, stems and other organs that are used to control gas exchange. They are produced in pairs with a gap between them that forms a stomatal pore.
- 5. A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. The saclike membranes that make up grana are known as thylakoids.
- 8. Rise The spontaneous movement of a liquid up thin tubes, due to adhesive and cohesive forces and surface tension.
- 11. One of the tiny openings in the epidermis of a plant, through which gases and water vapor pass.
- 12. The pointed protective sheath covering the emerging shoot in monocotyledons such as grasses.
- 15. The edible whole or coarsely ground grains of a cereal grass.
- 16. The upper petal of a papilionaceous corol.
- 20. a plant enzyme which catalyzes both the fixing of atmospheric carbon dioxide during photosynthesis and the reverse process of photorespiration. One of many enzymes in the Calvin cycle.
- 21. Any of a group of green pigments that absorb light energy used in photosynthesis and that are found in the chloroplasts of plants and other photosynthetic organisms such as cyanobacteria, especially.
- 23. The act of inserting a shoot or scion taken from one tree into the stem or some other part of another, in such a manner that they unite and produce fruit of the kind belonging to the tree from which the scion was taken.
- 24. The movement of a solvent (water in biological systems) through a differentially permeable membrane from a solution with high water concentration and low solute concentration Lemma
- 25. A substance used to destroy or inhibit the growth of plants, especially weeds.
- 28. A slender bristle, especially one at the tip of a glume or lemma in a grass spikelet. A bristle-shaped terminal or dorsal appendage, such as the beard of wheat, barley, and many grasses.
- 29. A n inflorescence in which the first flower is the terminal bud of the main stem and subsequent flowers develop as terminal buds of lateral stems.
- 30. A substance that destroys or inhibits the growth of fungi.
- 32. The exudation of water from leaves as a result of root pressure.
- 33. In C 4 grasses such as maize and some C 4 dicots, enlarged bundle sheath (BS) cells surround the veins (V) and the BS cells are then surrounded by mesophyll (M) cells. The pattern referred to as Kranz anatomy.
Down
- 1. Any of a large number of natural and synthetic materials, including manure and nitrogen, phosphorus, and potassium compounds, spread on or worked into soil to increase its capacity to support plant growth.
- 3. Sheath A layer or region of specialized cells surrounding a vascular bundle.
- 4. A stacked membranous structure within the chloroplasts of plants and green algae that contains the chlorophyll and is the site of the light reactions of photosynthesis.
- 6. A detached living portion of a plant (such as a bud or shoot) joined to a stock in grafting and usually supplying solely aerial parts to a graft.
- 7. Organelles within eukaryotic cells that produce adenosine triphosphate (ATP), the main energy molecule used by the cell .
- 9. A root system of a plant, often with a portion of the stem, to which a shoot or bud is grafted.
- 10. “Belly button” A small gap or opening in an organ through which connecting structures such as arteries, veins, nerves or ducts enter or leave. hilum. a scar located down one side of a seed indicating the point of attachment of the OVULE to the ovary.
- 13. Carboxylase Plays the key role of binding CO2 to create oxaloacetate in the mesophyll tissue.
- 14. The act or process of transpiring, especially through the stomata of plant tissue or the pores of the skin.
- 17. A type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site.
- 18. Oil plant, any of the numerous plants, either under cultivation or growing wild, used as sources of oil.
- 19. Sub-compartments of the inner membrane of mitochondria and are essential to mitochondrial function.
- 21. A protective sheath enclosing the embryonic root of grasses.
- 22. Division A method of asexual plant propagation, where the plant is broken up into two or more parts.
- 26. A dehiscent elongated, podlike fruit, characteristic of the mustard family, having two valves that fall away leaving a central partition as the fruit dries.
- 27. The interior of a membrane-bound compartment or organelle in a cell.
- 31. The colorless semiliquid material inside a chloroplast, in which the thylakoid membranes are embedded and where the dark reactions of photosynthesis occur.
