SIZE
Smallest cells Bacteria 1 micrometer
Largest cells Ostrich Egg - inches Nerve cell -
a meter
Most cells are less than 50 micrometers in
diameter. 100 to 400 human cells can span the
diameter of the head of a pin.
10
Q Why are most cells so small????
11
If a cell was the size of a classroom measuring
10 m in diameter then the diameters of the
following would be
Mitochondrion 1 m Prokaryotic Cell 2
m Ribosome 1 cm Protein 1
mm Atom .1 mm
12
ALL Cells have
Chromosomes that contain genes formed from DNA
A plasma membrane binding their contents
Cytosol the semifluid substance within the
membrane
Ribosomes that make proteins
13
Prokaryotes (before the nut)
DNA is concentrated in a region called a nucleiod
Little to no organization
Oldest type of cell (3 byo)
14
Eukaryotes (true nut)
True nucleus
Membrane enclosed organelles
Highly organized
1.5 byo
15
