Cell Theory

3.
All organisms are composed of one or more
cells.
The cell is the basic unit of structure and
organization of organisms.
All cells come from pre-existing cells.
Organelles

Small specialized structures that have a
specific function.


Contained in all cells.
Some are surrounded by membranes.
Prokaryotic Cells

Those cells that do not contain membranebound organelles.

Most unicellular organisms, such as bacteria, are
prokaryotes.
Eukaryotic Cells

Those cells that do contain membrane-bound
organelles.


Most multicellular organisms are eukaryotes.
(However, so are some single-celled organisms
such as amoeba.)
Nucleus

Central membrane-bound organelle which
controls all cellular functions in eukaryotes.
Benefits of Having MembraneBound Organelles


Separation of cell functions into distinct
compartments.
Ability to carry out various chemical reactions
at the same time.
