The correct answer is: B. Waxes
Waxes are a type of lipid that are found on the surface of plants. They help to protect the plant from water loss and abrasive damage. Waxes also help to reflect sunlight, which can help to keep the plant cool.
Leaves are the organs of photosynthesis in plants. They are responsible for converting sunlight into energy that the plant can use. Leaves are also responsible for gas exchange, which is the process by which plants take in carbon dioxide and release oxygen.
Minerals are essential nutrients for plants. They are used in a variety of plant processes, including photosynthesis, cell division, and nutrient transport. Minerals are also important for the structure of plant cells.
