PLS HELP ASAP If an animal cell wasn't in an isotonic solution, wouldn't active transport be able to balance the cell's volume?
ohaa [14]

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!
