1. Cell Structure
Note: Please do not have the students copy all of the information on these slides as notes, it is better to have them go through the slides and make comparisons of the cell parts/functions to parts/jobs in a school or city and notebook this or show you understanding on a whiteboard.
For example: a nucleus would be similar to the principal’s office in a school. The nucleus controls the cell and contains all the information for the running of the cell, while the principal’s office controls the cell and contains instructions for the running of the school. As you work through each slide, have students make those comparisons with each slide and show understanding in their notebooks, whiteboards, discussion, etc.

2. COMMON CELL TRAITS
A cell is the smallest unit that is capable of performing life functions.
Animal Cell
Plant Cell
Bacterial Cell
In your NB, create a T chart to list the major structures found in each cell.
Which cells are prokaryotes and eukaryotes? How do you know?

3. CELL WALL protects the cell gives shape is made of cellulose
A cell wall is found in plants, algae, fungi, & most bacteria.
Teacher note: have students use the graphic organizer “Parts of the Cell Chart” to record and review/study the material in this PowerPoint.
The cell wall is a boundary that protects.
Analogy: It can be compared to a fence around a property, or brick walls of a building that support the structure.

4. CELL MEMBRANE Outer covering, protective layer around ALL cells
For cells with cell walls,the cell membrane is inside the cell wall
Allows food, oxygen, & water into the cell & waste products out of the cell.
Cell membranes allow materials to enter or exit the cell.
Analogy:This could be like a security guard in a school that decides who can enter and exit the building.

5. CYTOPLASM gelatin-like inside cell membrane constantly flows
Cytoplasm is where the “action” of the cell occurs- chemicals flow and mix here.
Analogy: this could be the hallways and walkways where the “action” of the school occurs and students flow and mix.

6. NUCLEUS Directs all cell activities
Contains instructions for everything the cell does
These instructions are found on a hereditary material called DNA
Usually the largest organelle
Analogy: The principal of the school would represent the nucleus because he or she would be in control of what goes on throughout the entire school.

7. Quick Check! 1 2 4 3 Match the cell part to the job is does:
A. Controls the cell
B. Outer protective layer- in plants, not animals
C. Controls what enters and leaves the cell
D. Fills the cell, allowing chemical reactions to occur 2 1 4 3

8. MITOCHONDRIA Organelles that release energy from food
This energy is released by breaking down food into carbon dioxide
AKA the powerhouse b/c they release energy from food
Some muscle cells have 20,000 mitochondria
Analogy: The school cafeteria could represent the mitochondria. The cafeteria would be where all of the employees and students of the school get energy to function through the day by eating food.

9. VACUOLES Temporary storage spaces Store food, water, waste
Plant cells usually have larger vacuoles than animal cells
Analogy: Storage areas of the school, such as closets that hold books or other supplies, could represent vacuoles.

10. CHLOROPLASTS Green organelles that make food found only in plant cells
The job of chloroplasts in a cell is to convert energy from the sun into food for the cell.
Analogy:The solar panels on a school roof can convert solar energy into electricity that the school uses for lights and heat. This is alike to the function of chloroplasts in a cell because both convert solar energy into energy that they can use daily.

11. CHLOROPHYLL Found in chloroplasts
A green pigment that gives leaves & stems their color
Captures sunlight energy that is used to produce food called glucose
Glucose is a type of sugar
Analogy: the inner workings of the solar panel ( see analogy on previous slide)

12. Quick Check! 2 1structure that holds chlorophyll 4 3
green material that fills
the chloroplast
Match the cell part to the job is does:
A. Green pigment that traps light energy in plants
B. Storage compartment
C. Release energy for cell
D. Organelle that holds chlorophyll for food production in plants
1structure that holds chlorophyll 4 3

13. NAME THE ORGANELLE a. Nucleus c. Vacuole b. Chloroplast
d. Mitochondria

14. Compare Plant and Animal Cells
Create a Venn Diagram to compare and contrast a typical Plant and a typical Animal cell. You must include the following: cell wall, cell membrane, cytoplasm, nucleus,, mitochondria, vacuoles, chloroplast, chlorophyll.
