Quick Answer. Plants absorb energy from the sun and use photosynthesis to make sugars. Animals have mitochondria that use the sugars provided by plants to produce their own cellular energy. Plants that produce their own food, and food for other plants and animals using photosynthesis, are called autotrophs.
Within plant cells are chloroplasts (KLAWR-uh-PLASTS), organelles in which the energy from sunlight is used to make sugar. Plants use some of the sugar immediately, to keep their cells functioning. The rest of the sugar is stored in the cells. Animal cells do not contain chloroplasts.As a result, animals are not able to use the energy of the Sun directly. Instead, animals get their energy from food. Much of the food an animal uses for energy comes from the sugar that plant cells have stored.ithin plant cells are chloroplasts (KLAWR-uh-PLASTS), organelles in which the energy from sunlight is used to make sugar.
