How does a cell get rid of waste products such as carbon dioxide?

Cells get rid of the products like carbon dioxide out of the cells by the process known as cellular respiration.

The process of cellular respiration can be defined as the process by which the animals convert the energy into usable form and release the waste products such as carbon dioxide and water.

These products are released out of the body as a by-product of the combustion of energy.

The conversion of glucose into carbon dioxide and water is released in the outer environment which is used as a reactant for photosynthesis.
