Section 6.1 Plant Classification

• Chloroplast- where photosynthesis takes place.
• Chlorophyll- is a chemical that gives plants
  their green color and traps light energy.
• Photosynthesis- is the process in which plants
  use water, carbon dioxide, and energy from the
  sun to make food
• 6 CO2 6H2O C6H12O6 6O2
• Photosynthesis separates plants from animals
• Cell wall- give plant structure (No Bones)

2 Groups of plants

• Vascular- have tube like cells in their roots,
  stems and leaves to carry food and water. Most
  chloroplasts are in the leaves.
• Nonvascular- dont have tube like cells in their
  stems and leaves. Grow close to the ground in
  moist areas. No Roots! Hair like cells take up
  water by osmosis.

4

• Osmosis- is the movement of water across a cell
  membrane.

6.2 Nonvascular Plants

• Moss- is a small, nonvascular plant that has both
  stems and leaves but NO roots.
• Liverworts- no roots, stems or leaves. Is often
  flat, slippery layer of green cells that lies
  close to the ground.
• DIFFERENCE between mosses and liverworts is in
  the arrangement of the leavesLiverworts grow in
  2 or 3 flattened rowsMosses grow all around the
  stem

• Sexual Reproduction is the forming of a new
  organism by the union of sperm and egg.
• Fertilization joining of egg and sperm
• Non Vascular plants reproduce by spores.

6.3 Vascular Plants

• Xylem cells that carry water and dissolved
  mineral UP the roots to the leaves.
• Phloem cells that carry food made in the leaves
  DOWN to all parts of the plant.
• Fern vascular plant the reproduces with spores.

8
Conifers are plants that produce seeds in cones.

• Pine cones (left) and juniper berries (cones,
  right)
• Lumber supply ¾ is from Conifers.

9

• Seed is the part of a plant that contains a new
  young plant and stored food.
• Embryo is an organism in its earliest stages of
  growth.
• Pollen are tiny grains of seed plants in which
  sperm develop.

10
Flowering plant is a vascular plant that produces
seeds inside a flower.Flower is the
reproductive part of the plant. Male parts
produce pollen female produce eggs.There are
more flowering plants than non-flowering plants.
