Similarities and Differences Among Living things (organisms).


 

ORGANISMS    -Living Things-

A tree, a cow, a mushroom.bacteria (microscopic), and a student in your class,  are  all organisms , that are both similar and different from each other. Living things  are also  different from nonliving things. Can you name some characteristics that are similar among all living things? Ok how about naming a few differences among them. Try to explain your answers.

What is life?

There is  no agreement among scientists for a simple definition of life. All organisms share characteristics  shown only by living things.

Characetisics of living things:

  •    All  are organized structures – made of cells– that are the basic units of structure and function.
  • All use energy to perform all life activities including growth and development.
  • all organisms maintain
    homeostasis– their internal environment, regardless of an unstable external .environment.
  • All organisms reproduce by passing their (genetic) heredity information to new organisms (next generation )
  • Nonliving things have no functioning cells and no metabolic processes.Reproduction and maintenance of homeostasis are not  carried out.
