Across
- 4. specialized cell in the angiosperm phloem derived from the same parent cell as the closely associated, immediately adjacent sieve-tube member
- 5. substance applied to the foliage of plants to reduce water loss (transpiration)
- 6. raised strip of bark at the top of the branch union, where the growth and expansion of the trunk or parent stem and adjoining branch push the bark into a ridge
- 10. bud arising from a place other than a leaf axil or shoot tip, usually as a result of hormonal triggers
- 11. bud at the tip of a twig or shoot
- 14. waxy layer outside the epidermis of a leaf that reduces water loss and resists insect damage
- 15. area where a branch joins another branch or trunk that is created by the overlapping vascular tissues from both the branch and the trunk. Typically enlarged at the base of the branch
- 17. complex carbohydrate found in the cellular walls of the majority of plants and algae and certain fungi
- 18. compound, combining carbon, hydrogen, and oxygen, that is produced by plants as a result of photosynthesis. Sugars and starches
- 19. plant hormone involved in cell division, leaf expansion, and other physiological processes. Compounds with cytokinin-like activity may be synthetically produced
- 20. roots at the trunk base that help support the tree and equalize mechanical stress
- 21. plant with seeds borne in an ovary. Consists of 2 large groups: monocotyledons (grasses,palms, and related plants) and dicotyledons (most woody trees,shrubs,herbaceous plants, and related plants)
- 22. movement of water, minerals, or photosynthates longitudinally within a tree
- 25. meristematic tissue from which the corky, protective outer layer of bark is formed
- 26. red or purple pigment responsible for those colors in some parts of trees and other plants
- 27. 1-small lateral or terminal protuberance on the stem of a plant that may develop into a flower or shoot. 2-underdeveloped flower or shoot containing a meristematic growing point
- 29. specialized organelle found in some cells. Site of photosynthesis
- 31. growing point at the tips of shoots and roots
Down
- 1. process in which the development of cells in which the become specialized for various functions
- 2. natural defense process in trees by which chemical and physical boundaries are created that act to limit the spread of disease and decay in organisms
- 3. condition in which the terminal bud inhibits the growth and development of the lateral buds on the same stem formed during the same season
- 5. free spaces in plant tissue. Includes cell walls and intracellular spaces
- 7. fine, fibrous roots that take up water and minerals. most are within the top 12 inches of soil
- 8. aboveground roots. Usually adventitious in nature and sometimes having unique adaptive functions
- 9. plant hormone or substance that promotes or regulates the growth and development of plants. Produced at sites where cells are dividing primarily in the shoot tips. Auxin-like compounds may be synthetically produced
- 12. yellow, orange, or red pigment responsible for those colors in some parts of trees and other plants.
- 13. acronym for Compartmentalization Of Decay In Trees
- 16. area at the base of the petiole where cellular breakdown leads to leaf and fruit drop
- 18. thin layer(s) of meristematic cells that give rise (outward) to the phloem and (inward) to the xylem, increasing stem and root diameter
- 23. rounded or spreading growth habit of a tree crown
- 24. green pigment of plants found in chloroplasts. Captures the energy of the sun and is essential in photosynthesis
- 28. tree or other plant that sheds all of its leaves according to a genetically scheduled cycle as impacted by climate factors(usually during the cold season in temperate zones).
- 30. bud in the axial of a leaf. Lateral bud
