Chapter #6
Plants
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 plants1. Vascular- have tube like
cells in their roots, stems and leaves to carry food and water. Most chloroplasts are in the leaves.
2. Nonvascular- don’t 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.
• Osmosis- is the movement of water across a cell membrane.
• 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 leaves…Liverworts grow in 2 or 3 flattened rows…Mosses grow all around the stem
6.2 Nonvascular Plants
• 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.
Conifers are plants that produce seeds in cones.
• Pine cones (left) and juniper “berries” (cones, right) • Lumber supply ¾ is from Conifers.
• 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.
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.
