Plant Structure, Growth, and Reproduction
Show Answers:

  1. angiosperm, has one seed leaf, leaves veins are parallel, vascular bundles are scattered, floral parts are multiples of three(6), fibrous roots are shallow and branched
  2. angiosperm, has two seed leaves, leaves veins are branched, vascular bundles are in rings, floral parts are multiples of 4 or 5, taproot system (deeper in the ground, not highly branched)
    dicots (eudicots)
  3. anchors the plant in soil, absorbs and transports minerals and water, stores food, also root hairs increase surface area
    root system
  4. made of stems (for support), leaves (for photosynthesis), and flower (for reproduction)
    shoot system
  5. attachment point for leaves and flowers;
    portion of stem between node
    • node;
    • internode
  6. horizontal stem, grows along the ground, reproduces asexually (strawberries)
    stolons (runners)
  7. run either above or just below the surface of ground, function in reproduction, function in food storage, having buds can also form new plants
    rhizomes (root-like)
  8. located at the end of rhizomes, function is food storage, also reproduction (potatos of potato plant)
  9. part of leaf attached to the stem, function is store food and water (celery, long structure with leaves at the end)
    enlarged petioles
  10. structures used for climbing
  11. used for defense
  12. found above cellular level of organization, below orgal level, tissues form larger structures called organs
    plant tissues
  13. outer protective covering (epidermus) function= protection from things getting in and water loss, gas exchange
    dermal tissue system
  14. conducting tissues, function= transport things within plant, support
    vascular tissue system
  15. filler material between dermal and vascular system, function= storage and support and photosynthesis
    ground tissue system
  16. most abundant type of plant cell, function= metabolism, aerobic respiration, food storage, produces the other four types of cells
    parenchyma cells (in plants)
  17. provide support for plant while its still growing (strings of celery stalks)
    collenchyma cells (in plants)
  18. dead cells in plants, thick cell wall containing protein lignin
    sclerenchyma cells (in plants)
  19. located in sclerenchyma cells, long/slender cells, arranged in bundles
  20. located in sclerenchyma cells, shorter/thicker cells, hard coating, irregular (hardness on nuts and seeds)
  21. dead cells in plants, found in xylem tissue
    water-conducting cells (in plants)
  22. located in water-conducting cells, long/thin cells, tapered with cells
  23. located in water-conducting cells, wider/shorter cells, less tapered in cells
    vessel elements
  24. living cells in plants, phloem tissue, dont contain many organelles, companion cells share nutrients with this cell
    food-conducting cells (sieve-tube members)
