Question

A plant shows the following modifications: i) Leaves covered with dense hairs ii) leaf surface shiny or glabrous iii) leaf blade remains rolled during the day. The adaptation of the plant is to-
A. Conserve water
B. Prevent excessive heat
C. Check transpiration
D. Absorb water

Answer 1

In a biosphere only plants reside. The biosphere is a common factor which refers to the biodiversity world where we are also included. It includes- plants and animals majorly that how well animals are combined and sustaining or co-existing with the human world. plants live in a combined habitat over a long period of time for many years. The time scale can be measured in decades. Biodiversity is a variety of different organisms discovered millions of years ago.

Complete answer:
Option A: conserve water- leaves are the part of a plant which absorbs water and other nutrients as it is an aerial part of the plant. Leaves also absorb sunlight for the photosynthesis to occur.
Option A is not the correct answer.
Option B: prevent excessive heat- leaves release water from its surface when excessive water enters the cell sap. The veins and veinlets system in leaves helps in carrying nutrients to different parts of the plant.
Option B is not the correct answer.
Option C: check transpiration- leaves do check transpiration as to reach water to every part. transpiration decreases the pressure called hydrostatic pressure in plants due to which water easily moves upward due to this capillary action.
Option C is the correct answer.
Option D: absorb water- leaves apart from assembling nutrients and transportation, it absorbs water also but the shiny and glabrous parts are different.
Option D is not the correct answer.

Therefore, Option C is the correct answer.

Note:
Replacing the lost water in desert plants is a little tougher as compared to other plants. If the desert plants do not get enough water the plant can die. So, these plants acquired some adaptations to help them reduce water loss. Smaller, fewer pores than other plants with such pores hot and dry winds are prevented also nocturnal plants, desert plants act as nocturnal plants due the discussed reason transpiration occurring during day-time.
