Photosynthesis Write On Fourth Grade
Learner Expectation Content Standard: 3.0 Food Production and Energy for Life The 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.
In this activity you will: Learn about the process of photosynthesis Write a paragraph describing how plants use photosynthesis to live and grow
Plants need energy to grow Plants get energy from the sun Plants use energy to carry on the process of photosynthesis
Chlorophyll is needed for photosynthesis Chlorophyll is a green material in plants that traps light energy Chlorophyll is located in long, green cells Plants get their green color from chlorophyll Chlorophyll is needed for photosynthesis
Plants need air for photosynthesis Plants have tiny holes in the bottom of each leaf The tiny holes let air go in and out of the leaf Plants use a gas in the air called carbon dioxide Plants release oxygen back into the air
Plants need water for photosynthesis Plants get water from the soil Roots bring water from the soil to the plant Veins in each leaf carry water throughout the plan Water is needed for the cells of the plant to carry on photosynthesis
Plants need sunlight for photosynthesis Cells in the plant trap light energy from the sun Light energy helps change carbon dioxide and water to a simple sugar in plants The plant uses the simple sugars to help it grow
Photosynthesis helps plants live and grow! Photosynthesis is the process by which plants trap the suns energy Plants use the suns energy to change carbon dioxide and water into sugar
Writing Activity Explain how plants use photosynthesis to live and grow.
