Question

explain why red blood cells burst when placed in distilled water while plant cells rain intactwhy why red blood cells burst when placed in distilled water will plant cells remain intact

Answer 1

The lysis of the red blood cell is due to the osmotic pressure, mainly by chloride and sodium ions (250 mOsm/L).
A red blood cell placed in pure water undergoes considerable osmotic pressure. In the absence of back pressure applied in the cytoplasm, pure (hypotonic) water diffuses into the cell (hypertonic) through the membrane. The massive entry of water into the red blood cell leads to the swelling and then the bursting of the red blood cell, there is hemolysis of the cells

In plant cells, the cell wall restricts expansion, resulting in pressure on the cell wall inside, called turgor pressure.The vacuole, by its solute concentration (thus its osmotic pressure and its water potential) and in relation to the pressure exerted by the cell wall, regulates the turgor of the cell. This turgor is responsible for maintaining the cellular form and ultimately for the plant itself.
