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 plants 1. 2. Vascular- have tube like cells in their roots, stems and leaves to carry food and water. Most chloroplasts are in the leaves. 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. 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 leaves…Liverworts grow in 2 or 3 flattened rows…Mosses 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. 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.
