| Question | Answer |
|---|---|
| the smallest unit that can preform all life processes cells are covered by a membrane and have DNA and cytoplasm | cell |
| a phosphoric layer that covers and protects a cells surface; acts as a barrier between the cells environment | cell membrane |
| one of the small bodies in a cells cytoplasm that are specialized to perform a specific function | organelle |
| in a Eukaryota cell a membrane that contains (produces and stores) the cells DNA and processes such as growth and reproduction | nucleus |
| an organism that consists of a single cell that does not have a nucleus or membrane bound ogranelles | prokaryote |
| an organism made up of cells that have a nucleus enclosed by a membrane eukaryotes animals plant and fungi but not archaebacteria or eubacteria | eukaryote |
| a rigid structure that surrounds the cell membrane and provides support to the cell | cell wall |
| cell organelle composed of rna and protein; the site of proteins synthesis (makes protein) | ribosome |
| a system of folded membranes that assists in the production processing and transport (internal delivery system) of proteins and in the production of lipids | endoplasmic reticulum |
| in eukaryotic cells the cell organelle that is surround by two membranes and that is the site of cellulor repiration (cell power house, breaks down sugar to produce energy) | mitocondrion |
| cell organelle that helps make and package materials to be transported (distributed) out of the cell | golgi complex |
| contains materials in a eukaryotic cell | vesicle |
| a cell organelle that contains digestive enzymes | lyosome |
| a group of similar cells that perform a common function | tissue |
| a collection of tissues that carry out a specialized function of the body | organ |
| a group of organs that work together to perform body functions | organ system |
| a living thing any thing that can carry out life processes | organism |
| the arrangement of parts in an organism | structure |
| the special normal or proper activity of an organ or part | function |
| web of proteins in the cytoplasm keeps membrane from collapsing | cytoskeleton |
| organelles in which photosynthesis take place | cloroplast |
| worldssmallest cells have dna and ribosomes | eubacteria |
| reason cells are so small | surface area to volume ratio |
| fluid inside a cell | cytopasm |
