Golgi Apparatus
Makes and transports proteins and other material out of the cell. Finishing and Packaging
Cell Membrane
Regulates what enters and leaves the cell. Shipping and Receiving
Mitochondria
Breaks down food molecules to make energy. The Power Plant
Nucleus
Controls all cell activity and contains DNA. The Main Office
Vacuole
Stores water and other materials. The Warehouse
Nucleolus
Produces ribosomes
Cytoplasm
Contains all the organelles and provides the space for cell function to occur. The Factory Floor
Cell Wall
A protective wall made up of polysaccharides, maintains the shape of the cell
Ribosome
Builds proteins. Employees
Lysosome
Digests food particles and waste. Maintenance
Chloroplast
Contains chlorophyll, which makes the plant green and absorbs sunlight
Rough Endoplasmic Reticulum
Where ribosomes collect. Pathway that proteins and other materials travel through in the cell. The Assembly Line
Smooth Endoplasmic Reticulum
Carry materials around the cell- sometimes break down molecules
Cytoskeleton
Helps to maintain cell shape
Prokaryotic Cell
Don’t have a nucleus or organelles
Eukaryotic Cell
Has a nucleus and organelles
Cell Theory
- All living things are made of cells
- Cells are the structural and functional units of life
- All cells come from pre-existing cells
Selectively Permeable Membrane
It can “select” which molecules can come in and out of the cell
Passive Transport
Molecules moving from a higher concentration to a lower concentration that doesn’t require additional energy
Active Transport
The process by which molecules move across a cell membrane that requires additional energy
Endocytosis
The transport of a substance into a cell using energy
Exocytosis
Getting rid of a substance from a cell
Diffusion
The movement of molecules from a higher concentration to a lower concentration
Phagocytosis
The transport that engulfs a substance into a cell
Hypotonic
The dissolved substances surrounding the cell is lower than the concentration of the dissolved substances in the cell
Facilitated Diffusion
Passive transport across a membrane that uses transport proteins
Ion Pumps
The transport across the membrane that uses outside energy to go to a higher concentration of molecules
Ions
charged atoms or molecules
Pinocytosis
The transport that takes liquid into a cell
Hypertonic
The dissolved substances surrounding the cell is higher than the dissolved substances in the cell
