Transcript Prokaryotic vs. Eukaryotic Cells

Prokaryotic vs. Eukaryotic Cells
Prokaryotic vs. Eukaryotic Cells
Animal and Plant cells are considered eukaryotic cells.
Eukaryotic: A type of cell that has membrane-bound organelles
Bacteria are considered prokaryotic cells.
Prokaryotic: A type of cell that has no membrane-bound organelles.
Do Now: Getting sick
Describe the last time in your life when you got sick. How did
you feel? How long were you sick? How do you think you
got sick? How did you eventually get better?
Contagion
Why was everybody getting sick?

Compare/Contrast
Use your worksheet to compare and contrast the two images.
Prokaryotic Cells
Usually smaller than eukaryotic cells
In organisms like bacteria and archaea
Only a part of unicellular (one cell) organisms
Reproduce asexually
Have NO MEMBRANE BOUND ORGANELLES
Contain ribosomes, a cell membrane, cell wall, cytoplasm and sometimes flagella
DNA is in a circular shape called a plasmid in the cytoplasm
Eukaryotic Cells
Usually larger than prokaryotic cells
In animals, plants, fungi and protists
Can be part of unicellular or multicellular organisms
Reproduce sexually or asexually
Have MEMBRANE-BOUND ORGANELLES
(mitochondria, nucleus, chloroplast, vacuoles)
DNA is packed into linear structures called
chromosomes in the nucleus
All of these
Organisms are
made of
Eukaryotic Cells
Prokaryotic vs.
Eukaryotic DNA
Prokaryotic DNA: In a circular
chromosome called a plasmid that
floats in the cytoplasm.
Eukaryotic DNA: In linear
chromosomes inside of the nucleus.
Note- Chromosome = a package of
DNA
Do Now: 3-2-1
3 organelles that are in eukaryotic cells but not prokaryotic
cells
2 differences in prokaryotic and eukaryotic genetic material
1 difference in size between prokaryotic and eukaryotic cells

Cells and Health
Ways that prokaryotic
cells help us
Ways that eukaryotic cells
help us
Help digest food
We are made of eukaryotic cells so
they do everything for us!
Help prevent stomach ulcers
Think about it …
Angel is looking at a cell under a microscope.
She says that its eukaryotic. What is one
way that she can know that its eukaryotic?
A. She sees that it has ribosomes
B. She sees that it has mitochondria
C.She sees that it has a cell membrane
D.She sees that it has cytoplasm
Lab: The Battle of Prokaryotes and Eukaryotes
Question: Does plate A contain prokaryotic cells or eukaryotic cells?
Does plate B contain prokaryotic cells or eukaryotic cells?
