Question

Water logged soil is

• A. Physically as well as physiologically dry
• B. Physically wet but physiologically dry
• C. Physically dry
• D. Physically as well as physiologically wet

Answer 1

The correct option is B Physically wet but physiologically dry

A soil may be physically wet; but if the plants absorb the water only with difficulty, as in a salty marsh water logged soil, then the soil is physiologically dry. The halophytes are plants of physically wet but physiologically dry habitats. Such plants are commonly found near sea-shores where mesophytes and freshwater hydrophytes cannot thrive well. Although these plants grow in the areas which are well saturated with water yet they cannot avail of the water because of high concentration of salts in the soils.

Therefore, the correct answer is option B.
