Chloroplasts are organelles found in plant cells and some algae that allow plants to harvest energy from sunlight through a process called photosynthesis. During photosynthesis, specialized pigments in the chloroplast, including chlorophyll, absorb sunlight and use this energy to combine carbon dioxide and water to produce glucose and oxygen. This process helps plant cells manufacture glucose and other carbohydrates for energy storage. Photosynthetic cells, mainly found in leaves, can contain thousands of chloroplasts.
This worksheet includes questions related to chloroplasts and photosynthesis, such as the type of cells that contain chloroplasts, the energy source used by autotrophs to make their own food, the name of the food-making process, the raw materials for photosynthesis, the simple sugar produced, the gases used and released during photosynthesis, the location of photosynthetic cells in plants, the number of chloroplasts in photosynthetic cells, and whether animal cells have chloroplasts.
