In pure water, a red blood cell from an animal will swell and burst, but a leaf cell from a plant will not. Which structure in the leaf cell will prevent the plant cell from bursting?

cell membrane
|
|
|
cell wall

|
|
mitochondrion

|
nucleus

Explanation:
Detailed explanation-1: -Cell wall can withstand dilute hypotonic media and prevents bursting of cells. Therefore, plant cells withstand changes in environmental concentration much better than animal cells which get burst in such conditions.
Detailed explanation-2: -So, the correct answer is ‘Cells wall is rigid and does not get overstretched’
Detailed explanation-3: -The cell wall protects the plant cell from bursting due to the influx of water. Rather than bursting, the cell is able to withstand the osmotic pressure exerted by the water molecules. Consequently, the cell is kept turgid. Some plant cells have a cell wall comprised of a single layer.
