Plants for food and fiber
Across
- 3. the diffusion of water through a differentially permeable membrane.
- 4. the growing ovary of a plant that swells and protects the developing seeds until they are ripe.
- 8. the use of a system of large pipes and sprinklers to water crops.
- 12. process by which pollen, containing sperm , travels to the female cone.
- 13. the process in which water that is taken in by a plant or an animal evaporates from the organism.
- 15. the limiting of a crop to one particular type in an area in order to use energy and equipment efficiently
- 16. resources of nature are being renewed at least as richly as they are being used, and all wastes are able to be completely absorbed.
- 17. a practice whereby crops are rotated annually through carious fields, so that each crop is grown in a different field and pests have little opportunity to establish.
- 19. a process whereby the eggs of one plant are fertilized by sperm from another plant of the same species.
- 20. a process that involves choosing specific lanes with particular characteristics and encouraging these plants to reproduce.
- 23. a pigment in plants that makes leaves green.
- 26. a process used in plant reproduction whereby small sections of leaf and stem are cut from a parent land and grow into new plants.
Down
- 1. tendency of particles in gas or liquid to become evenly distributed by moving from areas of reader concentration to areas of lesser concentration.
- 2. the development of a seed into a new plant.
- 5. a single, ruminant root with numerous small roots coming out of it.
- 6. salt that has collected on the surface of soil.
- 7. movement of pollutants through levels of a food chain so that greater quantities are retained with movement up the food chain.
- 9. able to resist certain effects; insects become resistant to pesticides.
- 10. in the cells of living things, the process in which oxygen is used to get energy from food and is converted into carbon dioxide.
- 11. a shallow system of similar-sized than can quickly soak up moisture.
- 14. the tissue of lanes from the stem, leaves, seeds, or roots.
- 18. the process by which plants make their own food using sunlight.
- 21. the process of moving soil and rock from one place to another, mechanical weathering caused by the effects of wind and or water.
- 22. a process used in plant reproduction whereby a branch is taken from one tree and attached to another tree.
- 24. a process used in plant reproduction whereby plants reproduce from stems.
- 25. the dark-colored part of soil that is rich in nutrients, such as nitrogen, phosphorus, potassium, and sulphur.
