In biology vital functions are those that make all living things. There are three: nutrition, relationships and reproduction.
Function of nutrition
Living things take environmental nutrients and energy they need to live and throw out the middle waste substances they manufacture. Make the role of nutrition is that living things perform the following processes:
-Ingestion: It is the entrance of matter into the living being.
-Metabolism: Set of chemical reactions inside every cell of an organism and which can obtain energy and materials needed to live.
-Excretion: Expulsion to the outside of matter.

Function of relationship
It is the ability of living things to pick up signals from the environment (external and internal) and respond to them, ie makes us realize what is happening around us and act accordingly.
Function of reproduction
It is the ability of living organisms to produce new beings similar in their anatomy and their physiology to their parents.
There are two main types of reproduction: asexual and sexual reproduction:
Asexual reproduction occurs when specialized cells are not involved and there is no genetic exchange, so the offspring are genetically identical to its parent.
Sexual reproduction occurs when specialized cells involved (gametes) of different sex and occurs a mixture of genetic information contained therein.
