      1. Molses
      2. Antocers
      3. Hepatiques
  2. Seedles vascular plants:
    1. Have roots, stem and leaves but don't make seeds
      1. Tems
  3. Vascular plants:
    1. They have roots, stems, leaves and those special tubes for water and nutrients too
      1. Gymnosperms:
        These plants are special because they have neked seeds
      2. Angiosperms:
        Seeds inside fruits or flowers

  2. Sexual reproduction:

  1. 1. Meaning they make their own food substances from inorganic substances.
    1. 2. Water and minerals enter the plant through tiny roots hairs.
      1. 3. Carbon dioxide enters the plant the stomata.
        4. Once in the cells, water and carbon dioxide enter chloroplasts.
        5. The organic matter produced durning photosynthesis become sap and is distributed to the rest of the plant for nourishment.
