Answer:

C- Plant cells make their own food, but human cells do not.

Step-by-step explanation:

Animal cells must take food in from some other source. Plants, on the other hand, have the ability to make their own food through a process called photosynthesis. In essence, the plant cell uses the energy in sunlight to combine carbon dioxide and water to make molecules of glucose and to release oxygen.

D is wrong because the human body uses three types of molecules to yield the necessary energy to drive ATP synthesis: fats, proteins, and carbohydrates. Mitochondria are the main site for ATP synthesis in mammals, although some ATP is also synthesized in the cytoplasm.

A is wrong because plant cells obtain energy through a process called photosynthesis. Secondly, that energy is used to break down carbon dioxide and form glucose, the main energy molecule in plants. Plants, algae and some bacteria use photosynthesis to create energy used for growth, maintenance and reproduction.

B is wrong because food provides building materials for your body. Your body needs building materials so it can grow and repair itself. Specifically, it needs these materials to produce more cells and its components. Food contains substances that help control body processes.
