Answer:
Animal cells tend to do best in an isotonic environment, plant cells tend to do best in
a hypotonic environment. This is demonstrated in the attached PDF.
Explanation:
A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst) when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.
I hope this helps. If not I am really sorry!

<span>The question says, 'which component of a virus is lacking in a cell. The answer is capsid. virus capsid are protein shell of a virus, they envelope the virus and protect it from harm. Cells does not have capsid, they have rigid cell wall instead. The rigid cell wall protect the cell from harm and also give the cell shape.</span>
