- Photosynthesis is the process in which plants use sunlight to convert water and carbon dioxide into usable energy. According to 3dchem.com, glucose is the main carbohydrate produced during photosynthesis. Oxygen is produced as a byproduct of photosynthesis, which all animals need to support life.
- One way that plants use glucose is to form cellulose, which, according to "Science Clarified," makes up the cell walls of plants leaves and stems and provides dietary fiber for the animals and humans who consume the plants. "Science Clarified" explains that plants also convert glucose into starches, which can be stored as energy for later use.
- Sunlight is necessary for plants to carry out photosynthesis. According to BBC's GCSE Bitesize, other factors that affect photosynthesis are temperature, carbon dioxide concentration and the amount and intensity of sunlight a plant receives. BBC explains that these factors affect the speed of photosynthesis and the rate of glucose production.
