How do Plants Breathe?
Like any
other living organism, plants also breathe. They take
in oxygen and release
carbon dioxide by
the
process of respiration.
The oxygen
taken in is used for breaking down sugars that
the plant makes during photosynthesis,
and energy
and carbon
dioxide are released.
This energy is
used by plant for its growth and reproduction. About 40
per cent of the energy released
is
used up
and the
rest is lost as heat.
