Describe the usefulness of water in biosphere and biological systems.
Open in App
Solution
Water
is essential for all forms of life. It constitutes around 65% of the
human body and 95% of plants. Water plays an important role in the
biosphere owing to its high specific heat, thermal conductivity,
surface tension, dipole moment, and dielectric constant.
The
high heat of vapourization and heat of capacity of water helps in
moderating the climate and body temperature of all
living beings.
It
acts as a carrier of various nutrients required by plants and animals
for various metabolic reactions.
