A cell wall is a structural layer that surrounds some types of cells, situated outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides cells with both structural support and protection, and also acts as a filtering mechanism. Cell walls are present in plants, fungi and prokaryotic cells, where a major function is to act as pressure vessels, preventing over-expansion when water enters the cells. Cell walls are absent from mycoplasmas.

Explanation:
<span>All cells use oxygen to convert raw food products into energy they can use for health. In the process they make a bi-product which is carbon dioxide and waste material. If there was no cellular respiration the cell would die, because they would be lacking the oxygen needed for food conversion, and they would have no means of getting rid of their waste products.</span>
