notes on CELL FUNCTIONS (BIO):
Nutrition- the process by which cells obtain food molecules to support their other activities.
Digestion- the process by which food particles are broken down into smaller, soluble units suitable for cell use with the help of enzymes.
Absorption- the process by which cells absorb from their environment water, minerals and other materials essential to life.
Biosynthesis- the process by which all cells organize complex chemicals from simple building units or substances.
Excretion- the process by which by-products of all cell activities which are not needed for further cell functioning are eliminated.
Egestion- the process by which insoluble, undigested particles are eliminated by the cell. These egested particles have not been a part of any cellular metabolism.
Secretion- the process by which substances that are synthesized by the cells are expelled from the membrane. The elimination process influences extracellular activities and helps in the functioning of the body.
Movement- a process which includes the locomotion of cell by means of special structures like cilia or flagella.
Irritability- the process by which cells respond or react to external factors or conditions around them. Cells can alter their functions in response to changes in their environment.
Respiration- the process of breaking down food molecules into chemical energy needed by all cells in order to function.
Reproduction- a process by which a cell copies or replicates its DNA and increases its number by cell division. In reproduction, cells give rise to new cells thereby making organisms grow.
