Nucleus: Stores DNA for the cell.
Eukaryotic cell: Has a nucleus.
Prokaryotic cell: No nucleus.
Light microscope: uses lenses for focus.
Electron microscope: Creates beam of electrons for focus. It can be scanning, or transmission.
Cell fractionation: Taking a cell apart to study it.
Organelle: Organ for a cell.
Mitochondrion: A organelle that makes ATP (a kind of chemical energy) for the cell. Has it's own DNA.
Chloroplast: organelle in plant cells. Used for photosynthesis. Has it's own DNA.
Rough endoplasmic reticulum: Organelle in a cell. Has lots of ribosomes on it's surface, so it appears rough when looking at it through a microscope. Creates secretory proteins and membranes.
Smooth endoplasmic reticulum: Organelle in a cell. Does not have ribosomes on it surface, so it appears smooth when looking at it through a microscope. Used for metabolic processes.
Lysosome: Used to hydrolyse macromolecules.
Vesicle: Transporter in the cell.
peroxisomes: Creates toxic hydrogen peroxide away from the rest of the cell. Fortunately it can also turn hydrogen peroxide back into water.
Cytoskeleton; skeleton for the cell. Also used in cell motility when it interacts with motor proteins.
Cell wall: Extracellular structure of plant cells.
