UNIT 3: BIOLOGY
Tissues, Organs, and Organ Systems
MEET MARTY THE MARTIAN
• Marty was sent to Earth by the Martian government to find
life.
• Marty captured a car and brought it back to Mars.
• Marty must stand trial to determine if he met or failed to
perform his Martian duties.
• At the trial, Marty said:
• “I first saw these life forms rolling along roads in great
numbers.
• They were giving off thick clouds of poisonous waste
as they moved.
• They seemed to exhibit herding behavior, as many of
the cars moved in the same direction.
• They appeared to have a great deal of energy – some
of them moved greater than 60 km/hour!
• When one of these life forms stopped or slowed
down, the others behind it responded. They slowed
down and gave off a reddish light from the back, and
sometimes they made honking noises.
• I observed that they stopped to feed on a liquid
substance.”

The Cell Theory
Three main ideas:
1) All living organisms are made of one or more cells
2) The cell is the basic organizational unit of life
3) All cells come from pre-existing cells
