A minimum point used for comparison i think
Kile should know the answer because of the morphology (part of biology that studies the estructure and the form of something). The plant cell presents a rectangular form, while the animal's cells presents a round form.
There are other main differences. As their parts and the size. Before I explain that remember that a cell can be of two types eukaryotic (cell with nucleus) and prokaryote (cell with no nucleus). In the other they can be neurons, nefrons, etc...
The plant cell contains for example chloroplasts, cell wall and vascuoles; while animal's don't. Both of them have nucleus, cell plants are generally larger than animals. Those are the main differences.
Thankyou.

Cellular respiration is the process by which the body breaks down the sugar molecules that are eaten in food with the aid of oxygen and covert them into energy, carbon dioxide and water are also produced as by products. Cellular respiration and fermentation are both involved in the breaking down of sugars but cellular respiration occurs in the presence of oxygen while fermentation occurs in the absence of oxygen. Carbon dioxide is breath out by the lungs during cellular respiration.
