CELL THEORY

All living organisms are made up of cells.
CELL THEORY


Cells are the basic unit of structure and
function in an organism.
Cells control birth, growth, development,
reproduction and death. All life
functions begin as a cellular
process.
CELL THEORY


Organisms can be unicellular (one-celled)
or multicellular (many-celled)
Cells contain organelles ( some with
membranes), which are small structures
inside that do different jobs.
All cells come from other cells.
Cells can be classified into 2 groups.
Eukaryotic Cells
Prokaryotic Cells
Cells can be classified into 2 groups.
Eukaryotic Cells
Have a defined
nucleus.

Have a defined nucleus.
Found in organisms that
are made up of many

Plant Cell
Nucleus: Is the “brain” of the cell. It
controls cells’ functions and it contains
DNA.
Cell membrane (plasma membrane) :
Allows for certain things to enter and exit
the cell. It maintains cell’s homeostasis.
Ribosomes: Make proteins for the cells
Mitochondria: “power house of the cell”,
this is where cells receive their energy.
Cell Wall: Supports and protects plant
cells.
Chloroplast : Where plants absorb
sunlight, and make food (carbohydrates).
Let’s look at some actual
plant and animal cells!
