Structure of Living Things: Lesson 2
Cells to Organisms:
What do we already know?
1) 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
1) Do you think all animals have the same cells?
•
I’m not sure
Structure of Living Things: Lesson 2
Cells: Vocabulary Part I
1)
Unicellular: Made up of only one cell
2)
Organism: An individual living thing
3)
Multicellular: Made up of more than one cell
4)
Tissue: A group of similar cells that work together to do
the same jobs.
5)
Organ: A group of tissues that work together to perform
a specific bodily function
Structure of Living Things: Lesson 2
Cells: Vocabulary Part II
6)
Organ System: A group of organs that work together to
perform a specific bodily function
Structure of Living Things: Lesson 2
Cells to Organisms: Drawings
(pg. 40)
Structure of Living Things: Lesson 2
Cells to Organisms: Main Ideas
1) How are living things organized?
1) (See drawing on previous slide)
 Quick Check
-Compare and Contrast: What activities are common
to all living things?
All living things have cells, die,
breath, grow, eat and excrete.
Structure of Living Things: Lesson 2
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.

Cells to Organisms: Main Ideas
3) 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. Structure of Living Things: Lesson 2
