What is the difference between population and organism?
Ostrovityanka [42]

An organism describes an individual. You are an organism. I am an organism. The mosquito that flies by your window is an organism. An organism is a single, living thing and can be an animal, a plant, or a fungus. Organisms grow and respond to their environment.

A population is the term we use to describe multiple individuals or organisms of a single species that live within a particular geographic area. For example, there may be one population of painted turtles in one state and another population of painted turtles 250 miles away in another state.

serg [7]

Answer:

The answer is when the cell express different genes.

Explanation:

Cell differentiation is the process when a cell is changed from one cell type to an other and brings more complexity to the system. A cell before differentiation possess all the genes however their expression in turned off. When some external or internal factors trigger the gene expression it starts the cell differentiation. A multicellular organism undergoes several rounds of cell differentiation during its development. Although cell differentiation changes the size, shape and metabolic activity but the genetic makeup or DNA is never changed during cell differentiation.
