bacteria | prokaryotes that are the smallest cells that have ribosomes |
eukaryote | an organism made up of cells that have a nucleus enclosed by a membrane as well as membrane-bound organelles |
nucleus | in a eukaryotic cell, an organelle that contains the cell's DNA and that has a role in growth, metabolism, and reproduction... a large organelle that produces and stores the cell's DNA |
organelle | small bodies in a cell's cytoplasm that are specialized to perform specific functions |
prokaryote | an organism that consists of a single cell that does not have a nucleus or membrane-bound organelles |
ribosomes | tiny, round organelles made of protein and other material... make protein |
surface area-to-volume ratio | the reason most cells are limited to a very small size |
cytoplasm | the fluid inside a cell |
cell wall | a rigid structure that gives support to a cell |
chloroplasts | organelles in which photosynthesis takes place |
cytoskeleton | a web of proteins in the cytoplasm that keeps a cell's membrane from collapsing |
endoplasmic reticulum | a system of folded membranes that functions as the internal delivery system of a cell |
Golgi complex | the organelle that packages and distributes proteins |
lysosomes | organelles that contain digestive enzymes |
mitochondrion | an organelle that functions as the main power source of a cell, breaking down sugar to produce energy |
