Analogy Project
Do First
1. There are approximately 10 billion cells in the
human body. False; there are more than 100
TRILLION (100,000,000,000)
2. You have billions of bacteria inside your body right
now.
True!
3. Cells are about the size of atoms.
False! They are WAY bigger!
4. It is unhealthy to eat food containing
microorganisms (microscopic living things).
False! (sometimes)
5. Microorganisms cannot live in extreme heat or
cold.
False!
Do First
6. Bacteria make up about 1 percent of your dry body
weight.
False! They make up 10%!
7. Microorganisms produce some of the oxygen we
breathe.
True!
8.There are over 350 species of bacteria living inside
your mouth.
True!
9. Antibiotics kill viruses.
False! They kill bacteria
10.The bubonic plague bacteria was responsible for
killing one-third of the population in Europe.
True!
Today’s Objective:
 SWBAT
differentiate between
prokaryotic and eukaryotic cells.
The Two Types of Cells

As microscopes got
more powerful,
scientists started look
at the parts inside
cells.

An organelle is a
small, specialized
structure inside a
cell.
The Two Types of Cells
All cells can be divided into two
categories:
Eukaryotic Cells
Prokaryotic Cells
Prokaryotic cells (Pro rhymes with NO)
Prokaryotic Cells




Do NOT contain a nucleus or any other
membrane-bound organelles.
DNA floats around in the cytoplasm
Very small. Smaller than eukaryotic
cells.
Usually found in bacteria and other
unicellular organisms
Eukaryotic cells (Eu rhymes with True)
DNA
Eukaryotic cells




Contain a nucleus or any other
membrane-bound organelles.
DNA located in the nucleus.
Very large. Smaller than eukaryotic
cells.
Usually found in animals, plants,
fungus, protist and other
multicellular organisms
