Golgi
Definition
- Golgi Body, Golgi Apparatus or the Golgi Complex
- Membrane-bound structure that is the site of storgae and packaging of materials for vesicles to transport in and out of cells
- Vesicles are membrane-bound structure that export material out of cells
- When vesicles go to the edge of the cell the send out the materials
Term
Eurkaryotic Cells
Definition
- Complex and organsed cells that function well
- Have several membranes that cover each compartment in the cell such as organelles and a nucleus
- Examples are animals, plants or fungi
- Cell membrane
Term
Cell Membrane
Definition
- Outer covering, protective layer around a cell
- For cells with cell walls the membrane is inside
- Semi-Selectively Permible (Substances are able to get in and out)
Term
Cell Wall
Definition
- Lies outside the cell membrane
- Provides greater support and strength
- Protects the cell
- Gives shape
Term
Cytoplasm
Definition
- Semi-transparent fluid of the cell (gellitin like) that makes up the cytoplasm
- Cytoplasm includes all organelles and the cytoplasm is the site of cellular activities.
- Inside cell membrane
- Cytoplasm flowing lets nutrients pass throughout the cell
Term
Cytoskeleton
Definition
- Scaffolding - Gives structure in the cytoplasm
- Helps the cell maintain or change is shape
- Made of protein and microtubes
Term
Mitochondria
