Prokaryotic and Eukaryotic Cells
TSW – Recognize that the presence of a nucleus determines whether a cell is prokaryotic or eukaryotic. 6.12BSlide2
Cells
There are two
basic types
of cellsProkaryotes or prokaryotic cells Eukaryotes or eukaryotic cellsSlide3
Prokaryotes do not have a
nucleus
The
genetic material is bunched together, but is not found inside a nucleusThink PRO and NO
(no nucleus)
Prokaryotic
cells
Nucleus
Slide4
Prokaryotes
Prokaryotes are
single celled
organisms that sometimes live in colonies or groupsThey are ancient life forms that have been around for billions of yearsThey are less developed with only a few cell parts that can be identified under a microscope
However, they are able to
survive
a variety of conditions and live quite well on Earth.
Bacteria
are prokaryotesSlide5
Prokaryotic
Cell
G
enetic material is
not
found inside a nucleus
.Slide6
Eukaryotes
Eukaryotes are more
complex
cells than prokaryotesThey have a nucleus which contains the genetic material of the cellThey also have more identifiable cell parts
Think “
Eu
” pronounced “you” You are made up of complex eukaryotic cells.
YOUSlide7
Eukaryotes
Most
living things we are familiar with are eukaryotic.
This includes: all plants, all animals, all fungiSlide8
Eukaryotic Cell
Nucleus that contains
t
he genetic material of the
c
ell.
Notice this cell has more cell parts and is much more complex
.Slide9
Comparing cells
Notice the difference in size between the two cells.Slide10
Cell sizeSlide11
Summary
Prokaryotes
No nucleus
Smaller in sizeLess complexSingle celled organismsAncient life form
Bacteria is an example
Eukaryotes
Has a nucleus
Larger than prokaryotes
More complex
Can be single celled organism but all multi-celled organisms are eukaryotes
Plants, animals, fungi – all are eukaryotic Slide12
