3. Cells to Organisms: What do we already know?
What do you know about plant and animal cells?
Trillions of cells in your body
Each has different organelles
All cells have a nucleus
How are plant and animal cells different or the same?
Animal cells flex and plant cells are firm
Plant cells have chloroplasts
Do you think all animals have the same cells?
I’m not sure

4. Cells: Vocabulary Part I
Unicellular: Made up of only one cell
Organism: An individual living thing
Multicellular: Made up of more than one cell
Tissue: A group of similar cells that work together to do the same jobs.
Organ: A group of tissues that work together to perform a specific bodily function

8. Cells to Organisms: Main Ideas
1) How do cells work together?
They work together to perform the same task for the body.
Tasks such as: The stomach digests food, The stem soaks up water.
Quick Check
-Compare and contrast: How do organs compare to
organ systems?
An organ system is made up of organs.

9. Cells to Organisms: Main Ideas
What are some plant and animal organ
systems?
Plant: Root system and shoot
system
Animal: Digestive system
Quick Check
-Can an organ be part of two organ systems?
Yes, the salamander's skin is a part
of 2 systems.
