Organizer to take notes

*The cell is the smallest unit of a living thing.

*Some organisms are made of a single cell

[unicellular like Organism B in the previous slide]

*Some organisms are made up of many cells

[multicellular like Organism A in the previous slide]

*Each cell whether part of a unicellular organism or

a multicellular organism performs all the

activities that characterize life.

*Multicellular organisms are more complex than

unicellular organisms [the horse is a more complex

organism than the paramecium]
