Photosynthesis and Matter Cycling

Green plants and algae make their own food through photosynthesis. What is photosynthesis?

• a cell process that uses energy from sunlight to convert water and oxygen into food

• a cell process that uses energy from sunlight to convert water and glucose into food

• a cell process that uses energy from sunlight to convert water and chlorophyll into food

• a cell process that uses energy from sunlight to convert water and carbon dioxide into food
