2Learner ExpectationContent Standard: 3.0 Food Production and Energy for LifeThe student will study the basic parts of plants, investigate how plants produce food, and discover that plants and animals use food to sustain life.Learning Expectations:3.1 Realize that plants and animals use food for energy.3.2 Recognize the function of specific structures in organisms that allow them to obtain and use energy.
3In this activity you will: Learn about the process of photosynthesisWrite a paragraph describing how plants use photosynthesis to live and grow
4Plants need energy to grow Plants get energy from the sunPlants use energy to carry on the process of photosynthesis
5Chlorophyll is needed for photosynthesis Chlorophyll is a green material in plants that traps light energyChlorophyll is located in long, green cellsPlants get their green color from chlorophyllChlorophyll is needed for photosynthesis
6Plants need air for photosynthesis Plants have tiny holes in the bottom of each leafThe tiny holes let air go in and out of the leafPlants use a gas in the air called carbon dioxidePlants release oxygen back into the air
7Plants need water for photosynthesis Plants get water from the soilRoots bring water from the soil to the plantVeins in each leaf carry water throughout the planWater is needed for the cells of the plant to carry on photosynthesis
8Plants need sunlight for photosynthesis Cells in the plant trap light energy from the sunLight energy helps change carbon dioxide and water to a simple sugar in plantsThe plant uses the simple sugars to help it grow
9Photosynthesis helps plants live and grow! Photosynthesis is the process by which plants trap the sun’s energyPlants use the sun’s energy to change carbon dioxide and water into sugar
10Writing ActivityExplain how plants use photosynthesis to live and grow.
