2. Vocabulary
Cell wall- rigid layer that surrounds the cells of plants and some other organisms, mushrooms. Nucleus- cell’s control center directing all of the cell’s activities. Organelle- cell structures that are specialized and carry out specific jobs inside the cell. Ribosome- small grained organelles that produce proteins. Cytoplasm- gel-like fluid found inside the cell (cell membrane and nucleus) Mitochondria- convert the energy stored in food to energy the cell can use (rod-like structures) Endoplasmic reticulum (ER)-organelle with a network of membranes that produces many substances (move around proteins) Golgi apparatus- packages and distributes materials from ER. Vacuole- Stores water, food, wastes or other materials. Chloroplast- Makes food for cell during photosynthesis. Lysosome- Break down food particles and worn out part cells.

3. Looking Inside Cells A Typical Animal Cell
Each kind of cell structure has a different function within a cell.
Where is the cell membrane?

4. How Do the Parts of a Cell Work?
Cells contain a number of smaller structures that divide up the jobs inside the cell.
Each kind of cell structure has a different function within a cell.
Cell Wall rigid layer that surrounds the cells of plants and other organisms (mushrooms)= protects and support the cell
Cell wall made of CELLULOSE
Materials that pass through the cell wall= water & oxygen
Animal Cells= no cell wall

5. How Do the Parts of a Cell Work?
Every cell is surrounded by a cell membrane, which controls the movement of materials into and out of the cell. (kind of a screen)
Example of things that pass through the membrane:
Food particles
Water
Oxygen

6. How Do the Parts of a Cell Work? Pg 382
Organelles: cell structures that are specialized and carry out specific jobs inside the cell. (they are suspended in the cell’s gel-like fluid.)
nucleus directs the cell’s activities (functions similar as a brain, but is not a brain) (largest organelle)
nuclear envelope= surrounds the nucleus
Chromatin- within the nucleus, strand of DNA & Protein-has the information (411) for directing the cell’s functions.
Nucleolus- round structure in the nucleus, where ribosomes are made.
Ribosomes- small, grain shaped organelles that produce protein
Chromatin
Nuclear Envelope
Nucleolus

7. Organelles in the Cytoplasm pg 383
cytoplasm: gel-like fluid found inside the cell (cell membrane and nucleus)
mitochondria convert the energy stored in food to energy the cell can use (rod-like structures)
ribosomes produce proteins
endoplasmic recticulum and Golgi apparatus modify proteins and move them around inside the cell.
Vacuoles are structures where the cell can store water, food, or wastes.
lysosomes break down food into smaller particles
Chloroplasts-green plant cell that carries out photosynthesis.

8. How Do the Parts of a Cell Work?
Plant cells have two structures that are not found in animal cells: 1.) the cell wall-- surrounds the cell and helps support it 2.) Chloroplasts, captures the energy in sunlight to power the process the plant uses to make its own food.

9. Looking Inside Cells pg. 382,383
Ribosomes
Chromatin
Nucleolus
Nuclear
envelope
Pores
What does the nuclear envelope do?
In what types of cells would
you expect to find a lot of mitochondria?
What do ribosomes do?
Organelles of a Cell
The structures of a cell look as different as their functions. Where do you find these structures in the cell diagram?

10. Looking Inside Cells Plant Cell
These illustrations show typical structures found in plant cells.
What is the function of each structure?

11. Looking Inside Cells Animal Cell
These illustrations show typical structures found in animal cells.
What is the function of each structure?

12. Looking Inside Cells
Compare and contrast the structures present in plant cells and animal cells.

13. Looking Inside Cells pg. 386 Model for a Cell Function
Golgi Apparatus
How can this sentence be completed? The Golgi Apparatus is an organelle that ___________ and ___________ materials made in the __________.
Model for a Cell Function
How do the parts of a cell function in ways that are similar to the parts of a building?

14. Chloroplast Looking Inside Cells pg. 387
A chloroplast captures energy from sunlight and changes it
to a form of energy cells can use in making food. Chloroplasts make leaves green because leaf cells contain many chloroplasts.
