Question

Desert can be turned into green lands by planting

• A. oxylophytes
• B. psammophytes
• C. halophytes
• D. psychrophytes

Answer 1

The correct option is B psammophytes

Plants adapted to survive under the condition of very poor supply of available water in the habitats are called xerophytes.
Xerophilous plants are further classified on the basis of their habitats as follows:

(i) Oxylophytes (on acid soils)
(ii) Halophytes (on saline soils)
(iii) Psammophytes (on sand and gravels)
(iv)Psychrophytes (on cold soils)

Plants that have adapted to live in the desert with its high temperatures, constant winds and lack of moisture are called psammophytes. Almost all of them have small hard leaves. Long, often deep roots and thin stems allow them not only to get moisture from the stratum of sand and preserve it, but also hold them during sandstorms. They are often used to stabilize sandy soils. So they can be planted to turn deserts into green lands.
