Cell Membrane “Gate”
- Protects cell
- Allows things (water and nutrients) to move in and out of the cell
Cell Wall
- Plants only
- Protective barrier for plants
- Maintains cell shape
Chloroplast
- Plants only
- Contains chlorophyll (green pigment)
- Used in plant “digestion”
Chromosome
Thin strands within the nucleus of the cell
Cytoplasm
Everything in the cell except cell membrane and nucleus and nucleus (thick liquid and organelles)
Dehydration
Happens when cells lose more water than they take in
Diffusion
The movement of materials from an area with a lot of the material to an area with less of the material
Golgi Apparatus “manufacturing plant”
Packages things needed in the cell and gets them ready for transport elsewhere
Lysosome “garbage disposal”
- Helps digest food
- Break down invading organisms, cells when they die
- Could cause cell death if not monitored
Mitochondria “power house”
Provides the cell with energy
Nucleus “brain”
- Communicates with the cell
- Holds DNA
Organelles
Any cell structure with a specific job to do
Osmosis
Diffusion of water through a cell membrane
Endoplasmic Reticulum
- Combines proteins
- Packages proteins
- Exports proteins
Ribosome
Builds proteins
Vacuole “vacuum”
Storage (water, nutrients, etc.)
Which are only found in plant cells?

What are all three parts of the cell theory?
- All living things are made up of cells
- Cells are the basic unit of life
- Cells can only come from other cells
True or False: Even though all cells have similar parts, they can have different jobs (functions) or shapes?
True

Robert Hooke
In what material was the first cell discovered in?
Cork
What are the thin strands found in the nucleus of the cell, that contain instruction for the cell?
