Well, water by itself cannot diffuse into the cell easily, because of its polarity. The cell membrane ultimately determines how much water goes in and out of the cell by aquaporins and other channel proteins. Remember, the membrane is selectively permeable.
yes
Yes, cells are the bricks that form a living organism. Without regulation, they can't perform their vital functions.
The wall is irrelevant, because it is completely permeable- water can just pass straight through it. It is only there for structural support, the cell membrane is what determines what gets in and out of the cell.
Life wouldn't be without cells. Cells are living and make up living organisms.

No.
how do cells regulate synthesis to conserve energy
who care
All living things large enough to see without a microscope have cells.
cyclins regulate the timing of the cell cycle in eukaryotic cells,cancer cells do not respond to the signals that regulate the growth of most cells.
Yes all living things do posses cells because cells are what keep us alive. Without cells there would be no life on planet earth.
