|
|
Salt damages the cell walls of root cells.
|
|
|
The plant cells absorb too much water.
|
|
|
The transpiration rate is too high.
|
|
|
Water molecules diffuses out of the plant cells by osmosis.
|
Detailed explanation-1: -Plasmolysis is the shrinking of protoplasm away from the cell wall of a plant or bacterium. The protoplasmic shrinking is often due to water loss via exosmosis, thereby resulting in gaps between the cell wall and the plasma membrane.
Detailed explanation-2: -If a plant cell is surrounded by a solution that contains a higher concentration of water molecules than the solution inside the cell, water will enter the cell by osmosis and the plant cell will become turgid (firm).
Detailed explanation-3: -When a plant is watered, water moves into the plant by osmosis (the diffusion of water), this means that water moves into the cells causing them to become turgid.
Detailed explanation-4: -Capillary action is the phenomenon that causes water to rise from plant roots to leaves. Moisture is transported through plants via transpiration, from roots to tiny pores on the underside of leaves, where it transforms into vapour and is discharged into the atmosphere.
