Question

The sun-loving plants are referred to as

• A. halophytes
• B. heterotrophs
• C. sciophytes
• D. heliophytes

Answer 1

The correct option is D

heliophytes

The correct answer option D.

Explanation of the correct option:

1. The plants which grow in the presence of sunlight are called heliophytes or sun-loving plants.
2. Examples of heliophytes are mullein, thyme, white clover, and rose plants found in, rocks, meadows and mountains, and grasslands.
3. These plants have adapted themselves to withstand the heat emitted by the sun.
4. These plants require intensive light conditions as their metabolism requires high sunlight to grow.
5. These plants have tiny leaves with a waxy coating that protects against light radiation emitted by the sun.
6. The chloroplast present in the leaves of plants contains pigments that prevent the plants from infection.

Explanation of the incorrect options:

Option A:

1. The plants which grow under low light conditions are called sciophytes or dark-loving plants.
2. Examples of sciophytes include sunflower, Lycopodium which are commonly found in nurseries.

Option B:

1. The plants which grow in areas with high salt concentrations are called halophytes or salt-tolerant plants.
2. Examples of halophytes include mangrove trees found in marshy areas, saline deserts, and high salinity water bodies.

Option C:

1. The plants which cannot prepare their food but depend on other plants or organisms to derive their nutrition are called heterotrophs.
2. These plants may be parasitic(derives nutrition by living on other host plants), or saprophytic (derives nutrition from the dead and decaying matter)
3. Examples of saprophytic heterotrophs include mushrooms, Sarcodes sanguinea (snow plant), and parasitic heterotrophs are Cuscuta, Loranthus, Sandalwood tree, Mistletoe, and Red Bartsia.

Final answer: The sun-loving plants are referred to as heliophytes.
