What are the 4 major functions all cells perform?
They provide structure and support, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction.
What are 4 levels of organization?
An organism is made up of four levels of organization: cells, tissues, organs, and organ systems.
How does a cell carry out life function?
Cells carry on the many functions needed to sustain life. They grow and divide, thereby producing more cells. This requires that they take in nutrients, which they use to provide energy for the work that cells do and to make the materials that a cell or an organism needs.

What are the five basic needs functions of a living organism?
But because we are all living organisms, we all have five basic needs for survival: sunlight, water, air, habitat, and food. In different ways, these basic needs help keep our cells running the way they should.
Why is fire not considered alive?
The reason fire is non-living is because it does not have the eight characteristics of life. Also, fire is not made of cells. All living organisms is made of cells. Although fire needs oxygen to burn, this does not mean it is living.
