About This Lesson
Unlike us, plants do not depend on other plants or animals for food. They prepare their own food by a process called photosynthesis. Let's watch the video to know HOW?

Students know that mitochondria liberate energy for the work that cells do and that chloroplasts capture sunlight energy for photosynthesis.
Students know plants use carbon dioxide (CO 2 and energy from sunlight to build molecules of sugar and release oxygen).
Illustrate and explain how plants use the energy from light to make simple sugars, and more complex molecules, from carbon dioxide and water through a process called photosynthesis. Understand how this produces food that can be used immediately or stored for later use.
Recognize and describe that a key distinction among organisms is between autotrophs, such as green plants (which use energy from sunlight to make their own food), and heterotrophs, such as animals and fungi (which consume other organisms as food and harvest energy from them).
The major source of atmospheric oxygen is photosynthesis. Carbon dioxide is removed from the atmosphere and oxygen is released during photosynthesis.
Photosynthesis is carried on by green plants and other organisms containing chlorophyll. In this process, the Sun's energy is converted into and stored as chemical energy in the form of a sugar. The quantity of sugar molecules increases in green plants during photosynthesis in the presence of sunlight.
provide evidence that green plants make food and explain the significance of this process to other organisms.
Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.
Explain how energy from the Sun is transformed through photosynthesis to produce chemical energy in food.
Construct an illustration to explain how plants use light energy to convert carbon dioxide and water into a storable fuel, carbohydrates, and a waste product, oxygen, during the process of photosynthesis.
Recognize that plants use energy from the Sun, air, and water to make their own food.
Recognize that plants use energy from the sun to make sugar (i.e., glucose) by the process of photosynthesis.
Ask testable questions about the process by which plants use air, water, and energy from sunlight to produce sugars and plant materials needed for growth and reproduction.
