What is the cell theory?
1. All living things are made of cells
2. Cells are the basic unit of structure and function in living things
3. New cell are produced from existing cells
What is the Nucleus?
Large membrane -enclosed structure containing the cell's genetic information in the form of DNA
Where are Ribosomes located?
Attached to the Rough Endoplasmic Reticulum or free floating in the cytoplasm.
What does the Golgi Apparatus do?
packages, modifies, and sorts proteins for storage in the cell or secretion outside the cell
What is the path of Ribosomes?
1. Made in the DNA
2. Inserted in the Rough ER for modification
3. Moved to the Golgi Apparatus to be prepared for storage or movement
What does the Mitochondria do?
Converts the chemical energy of food into compounds that the cell can use.
What is the Cytoskeleton?

things/in out of the cell and Some have carbs attached to them, that acid in Communication between neighboring cells
Are particles moving or still?
They are moving, which causes them to spread out which leads to diffusion.
What is Diffusion?
Movement of particles from areas of high concentration to areas of low concentration
What does it mean when it says the cell wall is semi-permeable?
some molecules can freely move across it and some cannot
What is Active Transport?
Movement of materials across a cell membrane that DOES require energy from the cell.
What is Cell Specialization
The process of change within cells so that they have a specific function in an organism
