Active transport ---- Minerals

Explanation:
Stem tubers are plants which store their food in their stems. Potatoes are stem tubers.
Conditioned reflex is a reflex is acquired gradually by training in association with specific repeated external stimuli. For example, the Russian psychologist Ivan Pavlov's performed experiments on conditioned reflex using a dog. He demonstrated that a dog will salivate on the sound of a bell even if there is no food given to it if the ringing of the bell preceded every feeding session of the dog.
William Harvey discovered the circulation of blood and the function of the heart .
The islets of Langerhans found in the Pancreas secretes the hormone, insulin.
Autotrophs are organisms which are able to manufacture their own food, Blue green algae are examples of autotrophs.
Active transport is transport which requires expenditure of energy and occurs against the concentration gradient of the substance being transported. Because the concentration of minerals in the soil are in very low concentration, active transport is used by the root hair cells carrier proteins to move mineral ions across the membrane into the cell against the concentration gradient. ATP hydrolysis provides the energy for this process.
Chlorosis is a disease which appears as the yellowing of leaves in plants and in human a green tinging of the skin which is caused by the deficiency of minerals especially iron and manganese.
