Detailed explanation-1: -Answer and Explanation: If an animal cell was placed into a drop of 100% pure water, the cell would fill with water and would burst. This would happen due to the fact that the cell membrane is semi-permeable, allowing osmosis to occur.
Detailed explanation-2: -Cytolysis, also known as osmotic lysis, occurs when a cell bursts and releases its contents into the extracellular environment due to a great influx of water into the cell, far exceeding the capacity of the cell membrane to contain the extra volume.
Detailed explanation-3: -Unless an animal cell (such as the red blood cell in the top panel) has an adaptation that allows it to alter the osmotic uptake of water, it will lose too much water and shrivel up in a hypertonic environment. If placed in a hypotonic solution, water molecule s will enter the cell, causing it to swell and burst.
Detailed explanation-4: -Animal cells They swell and burst in a solution that is too dilute. In animals, the concentration of body fluids-blood plasma and tissue fluid-must be kept within strict limits-if cells lose or gain too much water by osmosis, they do not function efficiently.
