1. What are the reactants and products of photosynthesis? –Reactants = water, CO 2, and sunlight –Products = glucose and O 2

2. Fold your sheet in half.

3. Cut flaps on lines by cutting the first layer only.

4. Structure and function of plants

5. Open your foldable and label it like this. Structure Functions Adaptations

6. Flowers

7. Structure and Function Structure and Function Anther: produces pollen Pollen: haploid male gametes (sex cells) Stigma & Style: Sticky top of style where pollen lands. The style transports it to the ovary. Ovary: Female organ which produces female gametes.

9. Adaptation to Environment 1. Bright colors and sweet nectar to attract pollinators. 2. Development of fruit for seed dispersal.

10. Leaves

11. Leaf structure Greener on top CO 2 gets in here

12. Structure Upper Epidermis Palisade Layer Lower Epidermis Function contains cuticle prevents water loss Light reactions of photosynthesis. Lets CO 2 in and O 2 and water out (stomata)

13. Function of leaves Trap light energy for photosynthesis Produce sugar from photosynthesis Exchange of gases – carbon dioxide (in) and oxygen (out)

15. Structure Wide Helps to catch more light energy Thin Helps get carbon dioxide from bottom to top of leaf for photosynthesis

16. Stoma is a small hole Its size is controlled by 2 guard cells closed open

17. Stoma function is for gas exchange in the leaf Carbon dioxide oxygen Guard cell Provided plant is photosynthesising

18. Adaptations to environment Thick cuticle in dry climates. Few stomata to prevent water loss. Reduced surface area to prevent water loss. (cactus) Reduced surface area to prevent water loss. (cactus)

19. Stems

20. StructureXylemPhloemFunction vascular tissue (tubes) that carries water from the roots to other parts of the plant Vascular tissue that carries sugar (food)

21. Stems Stems can be herbaceous like the bendable stem of a daisy or woody like the trunk of an oak tree.

22. Adaptation to the Environment Stiff cell walls for trunks and branches. Dead Xylem becomes the wood on the inside of tree trunks. Can be modified to store food. ex: Tubers (potatoes) and Bulbs

23. Roots

24. Structure  Epidermis and root cap  Root hairs  Root tips (apical meristem) Function - protection and absorption of water and minerals. -increase surface area for absorption - tip of root that is growing into the soil (area of mitosis).

25. Wheat seed Root hairs Fragile parts of cells that grow from the main root They massively increase the surface area for absorption

26. Root ‘B’ has had the hairs damaged -

27. Adaptation to the Environment 1. Can be modified to store starch and sugar. (Carrots, Beets, Turnips) 2. In dry climates root systems can be extremely long to reach water.
