The plants which grow in marshy soil or salty are known as halophytes. In such conditions soil is completely filled with water and the oxygen disappears as well as amount of salts is excess. The characters of halophytes are as follows:
- Due to the absense of oxygen, these are known as respiratory roots.
- The amount of minerals in the soil is high, so exomosis may take place but in these plants mechanism of active transport occurs, So water doesn't move from inside to outside and roots absorb water from the soil.
- In the leaves of plants salt glands are present which help in the removal of salt and water from the body.
- Some halophytes absorb humidity by leaves due to the concentration of salts in the leaves.
