Question

The sun loving plants are referred to as
A. Halophytes
B. Heliophytes
C. Heterotrophs
D. Sciophytes

Answer 1

Hint:
The growth and development of the plants are greatly influenced by several factors present or absent in any habitat. These factors directly affect the development of the plants by affecting the different processes.

Complete Solution:
The sunlight is an important requirement for the process of photosynthesis and overall growth and reproduction in the plants. The sunlight obtained from the sun initiates the first process of photosynthesis and this process is also known as light dependent process of photosynthesis.

The amount of light in a particular habitat influences the food making activities on a direct basis. The green pigment of the plants are formed readily and in abundance in the presence of light. Light bears a peculiar relation to the nutrition and growth which determines their form and sizes.

Additional information:
Habitats are usually grouped with respect to the light and are divided into sun and shade. Sunny areas are the areas which receive good and ample amounts of sunlight. Areas such as meadows, pastures, fields and waste lands receive good amounts of sunlight. The areas which do not receive much sunlight are the shady areas and are the forests, grooves, woodland.

The spread of vegetation and growth are determined as the important factors for development of the plants. The plants which are the sun loving or the sun favouring plants are known as heliophytes. The halophytes are also known as sunstroke or sun loving plants. They are habituated with a very intensive insolation of the sun. They are common in open terrain, rocks, and meadows as well as at the mountain pastures and open grasslands.

These plants have adapted to these environments by bringing about certain changes in their body which includes presence of coarse tiny leaves with waxy and hairy protective covering that protects from light radiation and water loss. These plants bear double palisade layers and chloroplast have protective elements such as presence of carotenoid and enzymes. The plants have a higher light compensation point and they need a much higher illumination intensity for proper utilisation of carbon dioxide.

Therefore, the correct option is option B.

Note: The sun loving plants are also known as the heliophytes. These plants have accumulated certain modifications in order to withstand the increased availability of sun insolation and temperature. Various adaptations help the plants are helpful in surviving these conditions.
