Halophytes may show precell pressure very much higher than atmospheric pressure. Explain how this can happen.

Answers (1)

Halophytes are plants which are conditioned and have adapted to growing in a salt-based and concentrated environment. The concentration in the soil is much higher than the water present in the stem of the plant. Water potential is much less in the soil and can cause excessive water loss of the plant creating a stressful situation. Therefore the plants adapt to this situation by storing highly concentrated salts thus increasing the water potential of the soil and causing intake of water. This helps the plant to regulate and maintain its cell composition and pressure.
