7. Most Cells contain hereditary
information that is passed on
from cell to cell during
reproduction
All cells are basically
the same in chemical
structure and activities
8. Cell Diversity: Not all cells are alike
• Size and shape differ…this is related to the
function of cells
• Internal Organization…cells can be
specialized to perform different jobs
Ex: Pancreas cells (pictured
• Organelles – internal components that above) make insulin, while
perform different functions white blood cells (below)
digest unwanted microbes.
10. Prokaryotic Cells
• Bacteria
– LACK a NUCLEUS
and membrane
bound organelles
– Reproduce
asexually
– Contain genetic
material
11. PLANT CELL Eukaryotic Cells
• “Eu” – True cells
• CONTAIN a
NUCLEUS and
membrane bound
organelles
• Reproduces asexually
or sexually
• Contains genetic
material
• Ex. plant, animal,
fungi, algae
ANIMAL CELL
12. Virus
• Viruses lack cellular
structures and are
non-living
– Contain:
a. CAPSID – protein
coat
b. Can only contain
DNA or RNA
– Reproduce in a host
cell
– Ex. HPV, HIV, H1N1,
bacteriophage
