Across
- 5. – Energy transmitted in wave motion. Light.
- 7. – The parenchyma tissue between the upper and lower epidermis of a leaf; the cells usually contain chloroplasts.
- 8. – With three or more nerves, lobes, or leaflets radiating fanwise from a common basal point of attachment.
- 9. – The end of a branch, twig, etc.
- 12. – Minute objects within plant cells which contain the green pigment, chlorophyll.
- 15. – The main vein of a leaf; located halfway between the two edges. It is a continuation of the leaf stalk.
- 16. – Forking regularly and repeatedly, the two branches of each fork usually essentially equal.
- 18. – Leaf blades consisting of one unit.
- 21. – The stem of any leaf.
- 23. – A substance present in all green plants; it evidences itself as the green coloring in leaves. Transforms light energy from the sun into chemical energy for the manufacture of plant food from carbon dioxide, water, and essential soil minerals. This process is called photosynthesis.
- 26. – Tissues just below the epidermis of the leaf of a plant; most photosynthesis takes place in the palisade layers.
- 27. – In botany, the part of a leaf or branch attached to a stem or trunk.
- 28. – A leaf type that has veins running parallel to each other as in a blade of grass.
Down
- 1. – The edge, border, or borderline, as margin of a leaf.
- 2. – The process by which water vapor is released to the atmosphere by the leaves or other parts of a living plant.
- 3. – The expanded portion of a leaf.
- 4. – Designating the chemical changes that take place in living plant and animal cells whereby one compound is converted to one or more other compounds.
- 6. – A small, immature leaf. A separate division of a compound leaf.
- 10. – A group of related plants or animals that differs from other similar groups by characteristics too trivial or inconstant to be recognized as a species; often any category of lower rank than a species.
- 11. – Stalk, trunk, branch of a plant. Can be vertical or horizontal.
- 12. – A leaf composed, usually, of two or more leaflets.
- 13. – The cellular layer of an organism; the outer skin.
- 14. – Process by which green plants, using chlorophyll and the energy of sunlight, produce carbohydrates from water and carbon dioxide, and release oxygen.
- 17. – A common monosaccharide sugar that serves as the building block for many complex carbohydrates; blood sugar.
- 19. – In the naming of plants and animals, Latin is used. Each kind of plant or animal can be identified by genus (plural, genera) and species (both singular and plural); e.g., the generic name (genus) of corn is Zea and the species name is mays.
- 20. – Openings in the epidermal layer of plant tissues which leads to intercellular spaces. These small openings may open or close, depending on climatic conditions, by means of guard or bullform cells, etc., and are necessary to photosynthesis, transpiration, etc. Also called breathing pores.
- 22. – The arrangement of the veins in a leaf.
- 24. – A flattened outgrowth from a plant stem, varying in size and shape, usually green, which is concerned primarily with the manufacture of carbohydrates by photosynthesis.
- 25. – Constructed somewhat like a feather, with the parts (e.g., veins, lobes, branches) arranged along both sides of an axis, as in pinnate venation. A pinnate leaf is compound, with the leaflets arranged on both sides of the rachis.
