    multicellular, autotrophic, cell walls with cellulose, eukaryotic
  2. What did plants evolve from?
    Green algae (plant-like protist)
  3. Where does photosynthesis occur in plants?
    In chloroplasts in leaves
  4. What is the equation for photosynthesis?
    CO2 (carbon dioxide) + H2O (water) + light ----> C6H12O6 (glucose) + O2 (oxygen)
  5. What is the equation for cellular respiration?
    C6H12O6 (glucose) + O2 (oxygen) -----> CO2 (carbon dioxide) + H2O (water) + ATP
  6. Do plants undergo cellular respiration, photosynthesis, or both?
    Both
  7. Useable energy for all organisms
    ATP
  8. What is the order that plants evolved? (simplest to complex?)
    Mosses, ferns, gymnosperms, angiosperms
  9. What is the only nonvascular plant?
    Mosses
  10. What is a characteristic of nonvascular plant?
    They cannot grow tall because they don't have tissues to transport water and nutrients.
  11. What are the 3 groups of vascular plants?
    Ferns, Gymnosperms, and angiosperms
  12. Tissue in plants that helps transport water and nutrients throughout the plant
    Vascular tissue
  13. Vascular tissue that transports water
    Xylem
  14. Vascular tissue that transports food or nutrients
    phloem
  15. Structure that anchors plants and absorbs water and minerals
    roots
  16. Structure that supports the plant
    Stems
  17. What are the 2 groups of seedless plants?
    Mosses and ferns
  18. What are the 2 groups of seed plants?
    Gymnosperms and angiosperms
  19. What do seedless plants need in order to reproduce?
    water
  20. What is the advantage of seeds?
    Provides protection for developing embryo
  21. Cone-bearing plants
    gymnosperms
  22. How is pollination achieved in gymnosperms?
    Wind
  23. Flowering plants
    angiosperms
  24. What are the leaves of gymnosperms called?
    needles
  25. Where are the seeds located in gymnosperms?
    Cones
  26. What are the seeds located in for the angiosperms?
    Fruits
  27. What is the male reproductive part of a flower called?
    Stamen
  28. What two parts make up the stamen and what letters represent them in the diagram?
    Anther and filament
  29. What is the function of the anther?
    Produces pollen
  30. What is the female reproductve structure?
    Pistil
  31. What female part of the flower does the pollen first land?
    Stigma
  32. What structure becomes a fruit after the eggs are fertilized?
    Ovary
  33. What structure becomes seeds after they are fertilized?
    Ovules (eggs)
  34. What structre attracts pollinators?
    Petals
  35. You find a plant that has parallel veins in the leaves, fibrous roots, vascular bundles scattered, and 6 petals, Is this a monocot or dicot?
    Monocot
  36. You find a plant that has branching veins in the leaves, a taproot, vascular bundles in a ring and 10 petals. Is this a monocot or dicot?
    Dicot
  37. Seed leaf of a plant
    Cotyledon
  38. Whend oes pollination occur in plants?
    When pollen fertilizes the ovules
  39. When a plant slef-pollinates, is this sexual or asexual reproduction?
    Sexual reproduction because theire is mixing of pollen and egg.
  40. Pollen from a plant fertilizes the eggs of the same plant.
    Self pollination
  41. Pollen from a plant fertilizes the eggs of a different plant.
    Cross pollination
  42. What are 3 ways seeds are dispersed?
    water, wind, animals
  43. What are seeds dispersed by animals often contained in?
    Fruits
  44. What are 2 environmental factors that will cause a seed to come out of dormancy?
    Temperature and moisture (rain)
  45. Waxy covering on the top and underside of a leaf
    cuticle
  46. Where does the most photosynthesis occur in a leaf?
    palisades mesohyll
  47. Layer inside a leaf that has spaces for gasses to flow?
    spongy mesophyll
  48. WHat structure controls the opening and closing of the stoma?
    guard cells
  49. What structure is the opening for gas exchange?
    stoma
  50. What gas enters the leaf through the stoma?
    carbon dioxide
  51. What gas exits the leaf through the stoma?
    Oxygen
  52. If there is too much rain, do the guard cells open or close the stoma?
    Open to allow water to exit through the stoma
