GETTING RID OF WASTE
The cell makes waste in
producing all the materials it
does (proteins, lipids)
It needs a way to get rid of
the waste so it doesn’t build
up in the cell

LYSOSOMES
The lysosome has digestive enzymes that will break
down waste material.
Vacuoles can help in this process by storing
substances that need to be disposed of and sending
them to the lysosome to digest
The digested material will leave the
cell through the cell membrane

PROKARYOTES
Prokaryotes (like bacteria) are the simplest and
smallest cells
They do not have a nucleus and most other internal
parts of the cell
Because of this they cannot carry out
specialized functions
Pro- meaning before,
-karyote meaning seed

INSIDE PROKARYOTES
Prokaryotes have cytoplasm inside the cell
membrane
Their DNA is a simple loop that is inside the
cytoplasm
They also have a cell wall surrounding the cell
membrane that helps with structure and support
They do have ribosomes so they are able to make
their own proteins from the DNA they have

MOVEMENT OF
PROKARYOTES
Many prokaryotes also have flagella
These are long threadlike structures that help with
movement

EUKARYOTES
Eukaryotic cells evolved from prokaryotic cells
They have a nucleus that contains the cell’s DNA
They also have organelles which carry out activities in
the cell

EUKARYOTES
Eukaryotic cells can be unicellular (one cell) or
multicellular (more than one cell)
Unicellular organisms can carry out ALL of life’s
processes in that one cell
The bigger you are, the more complex you are
(multicellular)
