Cell Theory:
1.All living things are made of 1 or more cells
2.Cells are the basic unit of life
3.All cells come from other cells

Why is a skin cell different from a blood cell?
They have different functions!
Skin cell provides protection.
Blood cell carries oxygen.
*Use the levels of organization reading to complete
one:
Complete worksheet “Level 2” about the levels of
organization.
OR
Picture Drawing
*You may complete both for extra credit!
*1. What is the objective for today?
2. Identify the levels of organization from largest
to smallest.
3. What is more complex, a lung or the respiratory
system? Why?
4. Is a one celled bacterium considered an
organism? Why or why not?
5. Cells that are similar in structure and function
are joined together to form _________________.
*1. What is the objective for today?
2. Identify the levels of organization from largest
to smallest.
Organism, organ system, organ, tissue, cell
*1. What is more complex, a lung or the respiratory
system? Why?
Respiratory system because it is composed of many
organs working together. A lung is one individual
organ.
What organs does the respiratory system contain?
*1. Is a one celled bacterium considered an
organism? Why or why not?
Yes, because they undergo all the characteristics of
life. A single cell is the most basic and smallest
thing we consider to be living.
