Question

Give reason – Water acts as thermal buffer.
Draw a neat and proportionate diagram of root hair and label mitochondria, nucleus, and vacuole.

Hint:

Water’s thermal buffering is due to high specific heat; root hair organelles support absorption.

Answer 1

i. Reason: Water has a high specific heat capacity, allowing it to absorb and release large amounts of heat with minimal temperature change, stabilizing environmental and organismal temperatures.
ii. Diagram:
