1. PLANTS GROWTH AND ADAPTATION

2. Plants have 3 organs: 1. Leaves 2. Stems 3.Roots Draw the picture and Identify Structures.

3. LEAVES 1. Site of photosynthesis- chloroplasts in top layer of leaf. 2. Site of gas exchange- stomata in underside of leaf

4. STEMS 1. Provide structure for the plant 2. House vascular tissue –A. Xylem- tissue that draws water and minerals up from roots –B. Phloem- tissue that distributes sugar from leaves to rest of plant

5. ROOTS 1. Anchor plant to ground 2. Absorb water and minerals from soil

6. Plant Reproduction Plants have male and female reproductive parts.

7. Female reproductive structures The pistil -consists of the: 1.Stigma 2.Style 3. Ovary (contains the ovule, or plant egg)

8. Male reproductive structures The Stamen –consists of: –1. Anther –2. Filament –3. Pollen (plant sperm)

9. Plant Genetics Pollen is the male plant sex cell, or GAMETE. The Ovule is the female plant sex cell, or GAMETE. Gametes are HAPLOID- meaning that they each contain half the genetic material necessary to produce offspring. After fertilization, a genetically complete organism is formed, with all the genetic information necessary for survival and reproduction.

10. Fertilization Plant fertilization and seed distribution is carried out by insects, wind, and animals.

11. PHOTOSYNTHESIS Photosynthesis occurs in the chloroplasts O 2 is released and CO 2 is absorbed through the stomata

12. What happens during photosynthesis? Sunlight provides the energy for the chloroplast to convert carbon dioxide and water to glucose and oxygen. 6CO 2 + 6 H 2 O  C 6 H 12 O 6 + 6O 2

13. Plant Adaptations How do plants adapt to their environment? List some necessary characteristics for plants from the following environments: –1. Arid –2. Tropical Rain Forest –3. Cold, snowy climate –4. Temperature extremes

14. Pick My Environment Match the following plants to their proper environment.

15. VOCABULARY Copy and define the following: LeavesPollen StemsOvule RootsXylem ChloroplastPhloem HaploidStomata Photosynthesis GameteAdaptation

16. TEACHER NOTES Begin with “BrainPop”- “Plant Growth” and then “Photosynthesis” Have students create a book mark with the plant information. –Have them draw the leaves, stems and roots on one side, and define the terms on the other side. –Have them return their bookmark to their science teacher for extra credit!
