  26. Two main divisions in the plant kingdom- Vascular and Nonvascular
  27. Bryophytes- also known as Nonvascular plants
  28. Tracheophytes- also known as Vascular plants
  29. The 3 divisions of Bryophytes- Bryophyta, Hepatophyta, Antheocerophyta
  30. Division Bryophyta- Mosses
  31. Division Hepatophyta- Liverworts
  32. Division Antheocerophyta- Hornworts
  33. Vascular tissue- found in vascular plants, tissues that transport material throughout the plant
  34. Two types of vascular tissue- Xylem and Phloem
  35. Xylem- carries water and minerals from the roots to the stem and leaves
  36. Phloem- carries sugar form the leaves to where it is needed in the plant
  37. Seedless Vascular Plants- do not form flowers and seeds for reproduction , instead form SPORES
  38. Seed Producing Vascular Plants- produce seeds or flowers for reproduction, 2 divisions Angiosperms and Gymnosperms
  39. Angiosperms- Flowering plants that have seeds enclosed in fruit
  40. 2 divisions of Angiosperms- Monocots and Dicots
  41. Monocot- Angiosperms that have one seed leaf, have parallel veins, and flower parts come in 3’s Ex. grasses, bananas, corn
  42. Dicots- Angiosperms that have two seed leaves, have netted veins, and flowers come in 4 or 5’s Ex. Trees, roses, daisies
  43. Gymnosperms- produce seeds that are naked and not protected by fruit
  44. Sepal – encloses the bud and protects the flower while it is growing
  45. Petal- brightly colored, used to attract insects and other pollinators
  46. Stamen- the male part of the flower, 2 parts (Filament and Anther)
  47. Filament- supports the anther
  48. Anther- contains the pollen
  49. Pistil- the female part of the flower, 3 parts( Stigma, Style, Ovary)
  50. Stigma- sticky portion found at the tip of the style where pollen grains land
  51. Style- supports the stigma
  52. Ovary- where the eggs of the plant are found
  53. Mesophyll- contains chloroplast and is where nearly all photosynthetic activity take place in most plants
  54. Stomata- pore-like openings in the leaves of plants that allow CO2 and O2 to diffuse in and out of the plant
  55. Guard Cell- Control the opening and closing of the stomata
