In the purest sense, no you cannot live without water. Your body is made up of an estimated sixty percent water and it is vital for life functions. You can live for approximately three to four days without water. However, when you are asking if you can subsist on anything else, many things that you might choose do in fact contain water. Other drinks, even sodas have water content, as do many fruits and vegetables. It is possible to get enough hydration from sources other than pure water, but not to survive without it entirely.
For one thing based off of process of elimination we know that both plant and animal cells have a cell membrane, and a nucleus. Therefore we are left with cytoplasm and cell wall. According to the question we are most likely looking for something in the animal or plant cell that they don’t have in common with each other. Therefore, the answer is cell wall because an animal cell doesn’t have a cell wall, but a plant cell does. The cell wall can also make it more rigid!
