Plants do not have stomachs and cannot digest organic matter. It
is also a moot point whether organic molecules, which tend to be rather
large objects, can penetrate through the surface of the leaves into the
interior of the plant.

Plants do not have stomachs, but they process dissolved nutrients into a
growing medium, both through their leaves and through their roots. They
also process light into plant food by photosynthesis.


I believe that I am correct in saying that plants make use of only

inorganic
compounds as nutrients.
If anybody has actual evidence to prove me wrong, I will of course
apologise.


In another post I ghave acknowledged that plants can also absorb growth
hormones through their leaves.
