Question

Desert can be converted into a lush green land by planting:
A. Terrestrial plant
B. Mesophytic plant
C. Halophytes
D. Psammophytes

Answer 1

Hint: Plants that flourish well enough in desert conditions ought to retain moisture in their fleshy leaves or to have a broad root system. Desert plants thrive in hot and dry conditions where they would exist with minimal rainfall.

Complete answer:
Psammophytes are those produced in the desert that could really convert the desert into a lush green. Psammophytes are characterized by a range of modifications that allow them to exist on wind-blown sands. With such an area, plants are sometimes coated with sand or spread to their plant roots. It is indeed challenging for the seeds to sprout. Psammophytes trees and overgrown bushes from deep adventitious roots in all those parts of their trunk hidden in the sand. A number of Psammophytes are xerophytes and yearly ephemerals. Perennial Psammophytes have tiny, very small leaves or no leaflets at all, photosynthetic activity, and surface water of the stem. The fruits have wing-shaped appendices that allow them to travel with sand and reside on the surface of the sand. After germinating seeds (generally spring), the roots grow very rapidly and quickly hit a depth of approximately 0.5 m. During this depth, the sand persists moist till summer begins.
So, the correct answer is option (D).
Additional information:
Halophytes are those which flourish in saline environments. They are sodium plants that expand in soil or waterways of salinity stress, which comes in contact with saltwater through their roots or with salt splashes like semi-deserts, mangroves, and seahorses. Tropical trees seem to be the trees that are big in size and increasing in the tropics. Coconut palms and sea grapes also thrive along its shores of tropical islands. Other tropical trees comprise papaya, mango, and starfruit. Most tropical trees grow very rapidly. Just not a tree, China's massive bamboo is among the fastest rising plants that can rise up to 4 feet per day.

Note: Psammophytes are contained not just in desserts, and moreover along seas and marine waters and in sands along rivers. Psammophytes are widely used to strengthen sandy soils. It is obvious that Psammophytes and associated plants display variation in the shape and size of the leaf, flower, and fruit structures.
