  2. Parenchyma cells - ANS ✔thin-walled, living cells essential in photosynthesis and storage
  3. Petiole - ANS ✔the stalk or support axis of a leaf
  4. Phloem - ANS ✔plant vascular tissue that conducts photosynthates; situated to the inside of the bark
  5. Photosynthate - ANS ✔general term for the products of photosynthesis
  6. Photosynthesis - ANS ✔the process in green plants (and in some bacteria) by which light energy is used to form organic compounds from water and carbon dioxide
  7. Phototropism - ANS ✔influence of light on the direction of plant growth
  8. Radial transport - ANS ✔movement of substances in a tree perpendicular to the longitudinal axis of the tree
  9. Ray - ANS ✔tissues that extend radially across the xylem and phloem of a tree

Arborist

  1. Source - ANS ✔plant part that produces carbohydrates; mature leaves are sources
  2. Stomata - ANS ✔small pores between two guard cells on leaves and other green plants parts through which gases are exchanged
  3. Symbiosis - ANS ✔a mutually beneficial association of two different types of living organisms
  4. Tap root - ANS ✔central, vertical root that grows right below the trunk and is often choked off by the development of other roots
  5. Terminal bud - ANS ✔the bud on the end of a twig or shoot
  6. Tracheid - ANS ✔elongated, tapering xylem cell, adapted for support
  7. Transpiration - ANS ✔water vapor loss through the stomata of leaves
  8. Tropism - ANS ✔growth movement or variation of a plant as a response to an external stimulus such as light or gravity
  9. Vessels - ANS ✔stacked, tubelike, water-conducting cells in the xylem

Arborist

  1. Xylem - ANS ✔main water-and mineral-conducting tissue in trees and other plants; provides structural support and becomes wood after lignifying
  2. Meristems - ANS ✔New cells arise from the division of existing cells. In trees this process occurs in specialized zones called...
  3. Organs - ANS ✔plants have five ________: leaves, stems, roots, flowers and fruit
  4. Primary meristem - ANS ✔produce the cells that result in elongation of shoots and roots
  5. Secondary (lateral) meristem - ANS ✔produce cells that result in increases in diameter. Its what allows trees to grow so large.
  6. Cambium - ANS ✔the first lateral meristem. It is a thin sheath of dividing cells that produces the cells that become the vascular system of the tree
  7. Xylem, phloem - ANS ✔the cambium produces two kinds of tissue: _________ to the inside, and _________ to the outside
  8. Cork cambium - ANS ✔the second lateral meristem, it produces the bark
  9. Tracheids - ANS ✔are elongated dead cells with pointy ends and thickened walls, which function in water conduction and mechanical support.

Arborist

  1. Phloem - ANS ✔is responsible for the movement of sugars, produced in the leaves, to other plant parts.
  2. Sieve cells, sieve tube elements, companion cells - ANS ✔the phloem is composed primarily of living cells - ________ in conifers and _______ ______ ___________ and _________ _____ in hardwoods
  3. Axial transport - ANS ✔transports materials longitudinally
  4. Rays - ANS ✔are made up of parenchyma cells that grow radically in small layers that extend across the annual rings of phloem and xylem. They transport sugars and other compounds through the trunk, store starch, and assist in restricting decay in wood tissue
  5. First barrier wall - ANS ✔resists vertical decay spread by plugging xylem vessels
  6. Second barrier wall - ANS ✔resists inward decay spread by the more compact latewood cells and by depositing chemicals in these cells
  7. Third barrier wall - ANS ✔inhibits lateral decay spread by activating ray cells to resist decay.
