1. Kingdom: Plantae

2. Plants Chapter 21-24 Plant Basics
Almost all plants have chloroplasts which contain chlorophyll.
Chlorophyll is a chemical that gives plants their green color and traps light energy.
Plants trap light energy for photosynthesis.
Photosynthesis is the process in which plants use water, carbon dioxide, and energy from the sun to make food.

3. How plants are Grouped
Vascular- plants that have tube like cells in their roots, stems, and leaves to carry food and water.
Example: ferns, trees, seed plants, flowers
Nonvascular- plants that do not have tube like cells in their stems and leaves. Instead use osmosis to take up water and minerals.
Example: moss, liverworts

4. Nonvascular Plants

5. What is a plant? Eukaryotic Multicellular Autotroph
Cell wall composed of cellulose

6. Movement & Support Cell wall with cellulose Roots, stems, rhizoids
Nastic movement
Sclerenchyma & collenchyma

7. Digestion/Obtaining Nutrients
Autotroph
Chloroplast/chlorophyll
Leaves
Roots
Ingesting other organisms

8. Nervous/Response Nucleus Trichomes to secrete toxins
Leaf modifications
Hormones – growth, ripening
Photoperiodism

9. Tropisms

10. Circulation Root Stem Vascular tissue (in vascular plants..duh)
Xylem- carries water and minerals
Phloem- carries food
Osmosis and diffusion

11. Gas Exchange
Stomata in stems and leaves
Guard cells
Osmosis

12. Excretion
Stomata and guard cells

13. Reproduction Asexual and sexual
Sexual – flower, cone; pollen grains, ovules, fruits with seeds
Asexual – spores, roots, bulbs, cuttings (leaves), stems

14. Seed dispersal

15. Helpful Plants Produce oxygen Lumber Used to make paper
Erosion prevention

16. Landscape

17. Food

18. Medicine – marijuana, digitalis (heart medication), opium

19. Harmful Plants
Poison ivy, poison oak, poison sumac

20. Stinging nettles
Nightshade – poison
Weeds
Allergies caused by pollen
Invasive species – plants that move into an area and crowd out the original species of plants
