Leaves EQ: How do I describe the function of leaves? • Most numerous part to a plant • Role – capture the sun’s energy and carry out the food making process of photosynthesis
Leaf Structure • Bottom and top layers which protect cells • Leaf veins that contain the xylem and phloem • Stomata – • underside of leaf has small pores or openings • Opens and closes to control the amount of gas that enters and leaves the leaf EQ: How do I describe the function of leaves?
Leaf and Photosynthesis • Top layer of leaf contains chloroplasts • Chlorophyll in the chloroplasts trap sun’s energy EQ: How do I describe the function of leaves?
Leaf and Photosynthesis • Carbon Dioxide enters the leaf through the stomata • Water, which is absorbed by the plants roots, travels up to plant through xylem • Sugar and oxygen are produced from the CO2and O2. EQ: How do I describe the function of leaves?
Leaf and Photosynthesis • Oxygen exits leaf through stomata • Sugar enters the phloem and then travels throughout the plant EQ: How do I describe the function of leaves?
Controlling Water Loss • Transpiration – process by which water evaporates from a plant’s leaves • Plants slow down transpiration by closing the stomata EQ: How do I describe the function of leaves?
