Living organisms are cell-based systems that can perform life tasks such as reproduction, metabolism, stimulus response, and homeostasis.
Living organisms that have died or inanimate objects that have never been alive are both considered nonliving.
Life functions are following below:
Cellular structure- Individual parts of the cell structure each have a specific purpose that is necessary to carry out life's processes.
Growth. - The term "growth" describes an increase in the size and mass of an organ or a body. Cell proliferation and an increase in intracellular material are normally how it happens.
Reproduction- An organism reproduces an offspring that is biologically similar to the organism through the biological process of reproduction.
Response to stimuli- Process that causes a cell or organism to change its state or activity as a result to a stimulus (in terms of movement, secretion, enzyme synthesis, gene expression, etc.).
Respiration- Respiration is the process by which carbon dioxide is eliminated from tissues and oxygen is transported from the outside environment to cells within tissues.
Excretion-Excretion is a biological procedure that helps eliminate harmful substances and metabolic waste from an organism's body.
Movement - Excretion is a biological procedure that helps eliminate harmful substances and metabolic waste from an organism's body.
Definite Lifespan.-Life expectancy is the average number of years that a person lives, whereas life span is the maximum number of years that a person can live.
