|
Cell wall |
Made out of cellulose Found in plant cells Provides structure and function |
|
|
Cell membrane |
Made of proteins and phospholipid bilayer Found in all cells Regulates what enters and leaves the cell |
|
|
Prokaryotic cells |
Do not contain a nucleus No membrane bound organelles |
|
|
Eukaryotic Cells |
Cells that have a nucleus Contain membrane bound organelles |
|
|
Organelle |
structures found inside cells that have specific functions |
|
|
Mitochondria/Mitochondrion |
converts stored chemical energy into usable chemical energy for the cell |
|
|
Ribosome |
site of protein synthesis |
|
|
Lysosome |
contains digestive enzymes to break down unwanted parts of the cell |
|
|
Osmosis |
movement of water from areas of higher water concentration to areas of lower water concentration
movement of water from areas of lower solute concentration to areas of higher solute concentration |
|
|
Smooth Endoplasmic Reticulum |
site of lipid assembly |
|
|
Golgi Apparatus |
Makes final modifications of proteins and packages proteins for export or storage |
|
|
Nucleus |
stores genetic material (DNA) |
|
|
Nucelolus |
specialized part of nucleus where ribosomes are assembled |
|
|
Cytoplasm |
cushions, suspends and protects organelles in cell jell like substance |
|
|
Rough Endoplasmic Reticulum |
Modifies and transports proteins |
|
|
Centriole |
only in animal cells involved in cell division |
|
|
Cytoskeleton |
provides shape and structure to cell and aids in movement across the cell as well as cell movement |
|
|
Diffusion |
molecular movement from an area of higher concentration to an area of lower concentration |
|
|
Equilibrium |
Molecular movement is equal and concentration is equal |
|
|
Isotonic |
equilibrium has been reached Solute concentration inside and outside the membrane is the same |
|
|
Hypertonic |
Water moves out of cell Solute concentration is higher outside cell than inside the cell |
|
|
Hypotonic |
water moves into the cell Solute concentration is higher inside of cell than outside the cell. |
|
|
Cell theory (3 parts) |
Cells come from preexisting (other) cells Cells are smallest unit of life All living things are made of one or more cell |
|
|
Surface Area to Volume Ratio |
as a cell gets bigger the surface area to volume ratio decreases Important because limits how big a cell can be. |
|
|
Endocytosis |
Movement into a cell by infolding of the membrane |
|
|
Exocytosis |
Movement out of cell by outfolding of the membrane |
|
|
Phagocytosis |
Endocytosis of solids |
|
|
Pinocyctosis |
Endocytosis of liquids |
