Calcium also plays a role in the
plant very similar to a hormone in the
regulation of various cell functions.
One such function is in the regulation
of the protein pump that regulates the
uptake and movement of nutrients
into the root and throughout cells
within the plant. At the root level,
calcium activates stimulation of the
protein channels that take up
nutrients. Adequate availability of
calcium at the root surface is required
for this process to work effectively
