Cell Parts


Shipping/Receiving Department

- Cell membrane

- Controls what enters and leaves cell

1


Chief Executive Officer or President of Company

- Nucleus

- Contains chromosomes; directs cell activity

Very Important Information (blueprint)

- Chromosomes

- Made of DNA; stores genetic information about traits

Final Product

- Protein

- Transport oxygen, digest food, hair, eye color


Proteins are inside, outside, and on all types of cells.


Proteins are inside, outside, and on all types of cells.


Factory Floor – Where the action takes place

- Cytoplasm

- All life reactions take place here

Workers on Assembly Line

- Ribosomes

  • Black dots

  • Millions per cell

- Site of protein production

Assembly Line

- Endoplasmic Reticulum (ER)

- Folds proteins after proteins have been made

Finishing/Packaging Department

- Golgi Body

- Packages proteins that will be secreted from cell

Maintenance Crew

- Lysosomes

- Removes cell waste

Extra Support for some factories

- Cell Wall

- Gives plant cells support


9


Powerplant

- Mitochondria

- “Powerhouse of cell”; converts glucose to usable energy

Solar Powerplant for some factories

- Chloroplast

- Helps plants convert water and carbon dioxide into sugar during photosynthesis

Storage Room

- Vacuole

- A container to store food and water. Plants have large vacuoles

Microscope, Cell Theory, and Cell Parts Review


  • Which part is the:

  • stage?

  • Eyepiece?

  • Coarse focus?

If the eyepiece is 10x, the objective is 40x, and the thickness of the lens is 0.1 mm, what is the overall magnification?


Which parts should you hold when carrying the microscope?

  • When you start to observe a slide:

  • With which power should you begin?


  • ___________________ are made of cells.
