If a cell has the ability to take in water, food molecules, and other necessary materials this indicates it is capable of

The right answer is Nutrition

This answer can not be digestion nor absorption because it is a term that concerns multicellular beings.

Digestion is a mode of mechanical and chemical transformation of food nutrients assimilable or not by the body. By definition, digestion is a process present in all heterotrophic organisms. This digestion is carried out in a digestive system that can correspond to a simple digestive vacuole of a eubacterium, or specialize as is the case of mammals ruminants (cow, etc.). Digestion can also be defined as the molecular simplification that is to say the transformation of macromolecules (large molecules) into micromolecules.

Nutrition is therefore the most adequate answer.

By cellular nutrition is therefore meant the provision of the nutrients necessary for the proper functioning of each human cell. It is therefore to give the cells all the micronutrients at higher or optimal doses, that is to say in amounts beneficial to health. In other words, it is essential that our dietary supplementation be balanced and complete, as is a healthy diet.
