Which kingdom uses photosynthesis to produce food, is multicellular, and has cell walls?

Plants Fungi Animals Monotremes

Correct Answer:

Plants

Explanation:

Photosynthesis is how some organisms turn light energy into food, producing sugars from carbon dioxide and water. Plants do this, and they are multicellular organisms with rigid cell walls made of cellulose that give them structure. Fungi also have cell walls, but they don’t photosynthesize; they obtain nutrients by absorbing them from their surroundings. Animals, including monotremes, don’t have cell walls and don’t perform photosynthesis. So the combination of using light to make food, being multicellular, and having cellulose cell walls points to plants.
