Structure and Function of Plants Review and Foldable Fold your sheet in half along the crease line. Cut flaps on folds by cutting the first layer only. Structures Functions Open your foldable and label it like this. Fill in your foldable with the notes provided. Structure will go on one side and function will go on the other. Adaptations to the environment will go on the back. PLANTS Structure And Function Obj: 10 B Flowers Structure Function Anther -produces pollen Pollen -haploid male gametes (sex cells) stamen -contains pollen Stigma & Style -Sticky top of style where pollen lands. The Style transports it to the ovary. Ovary -Female organ which produces female gametes Adaptation to Environment 1. Bright colors and sweet nectar to attract pollinators. 2. Development of Fruit for seed dispersal. Flower Leaves Structure Function Upper Epidermis -contains cuticle prevents water loss Palisade Layer -Light reactions of photosynthesis. Spongy Layer -Calvin cycle (stores CO2) Lower Epidermis -Lets CO2 in and O2 and water out (stomata) Adaptation to Environment 1.Thick cuticle in dry climates. 2.Few stomata to prevent water loss. 3.Reduced surface area to prevent water loss. (Cactus) Leaves upper Lower epidermis Stems Structure Xylem Function -vascular tissue (tubes) that carry water from the roots to the leaves for photosynthesis and to other parts of the plant. -Vascular tissue (tubes) Phloem that carry sugar from the leaves to other parts of the plant. Adaptation to the Environment 1.Stiff cell walls for trunks and branches. Dead Xylem becomes the wood on the inside of tree trunks. 2. Can be modified to store food. Ex. Tubers (potatoes) and Bulbs Stem Roots Structure Function Epidermis -protection and and root absorption of cap water and minerals. -increase surface Root hairs area for absorption Root tips - tip of root that is (apical growing into the meristem) soil (area of mitosis). 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. Roots
