| Question | Answer |
|---|---|
| A microscope that uses a beam of visible light passing through one or more lenses to magnify an object. | Light Microscope |
| A microscope that focuses a beam of electrons to magnify objects. | Electron Microscope |
| The increase of an object's apparent size by using lenses or mirrors. | Magnification |
| In microscope, the ability to form images with fine detail. | Resolution |
| A microscope that produces an enlarged, three-dimensional image of an object by using a beam of electron rather than light. | Scanning Tunneling Microscope |
| The theory that states that all living things are made up of cells, that cells are the basic units of organisms,that each cell in a multicelluar organisms has a specific job, and that cells come only from existing cells. | Cell Theory |
| A phospholipid layer that covers a cell's surface and acts as a barriar between the inside of a cell and a cell's environment. | Cell Membrane |
| The region of the cell within the membrane that includes the fluid, the cytoskeleton, and all of the organelles except the nucleus. | Cytoplasm |
| The cytoplasmic network of protein filaments that plays an essential role in cell movement, shape, and division. | Cytoskeleton |
| A cell organelle composed of RNA nd protein; the site of protein synthesis. | Ribosome |
| An organism that consists of a single cell that does not have a nucleus or cell organelles; an example is a bacterium. | Prokaryote |
| A rigid structure that surrounds the cell membrane and provides support to the cell. | Cell Wall |
| A long, hairlike structure that grows out of a cell and enables the cell to move. | Flagellum |
| An organism made up of cells that have a nucleus enclosed by a membrane, multiple chromosomes, and a mitotic cycle; eukaryotes include animals, plants, and fungi but not bacteria or cyanobacteria. | Eukaryote |
| In a eukaryote cell, biology, a membrane-bound organelle that contains the cell's DNA and that has a role in processes such as growth, metabolism, and reproduction. | Nucleus |
| One of the small bodies that are found in the cytoplasm of a cell and that are specialized to perform a spcific function. | Organelle |
| A hairlike structure arranged in tightly packed rows that projects from the surface of some cells. | Cilium |
| A lipid that contains phosphorus and that ia a structural component in cell membranes. | Phospholipid |
| The basic structure of a biological membrane, composed of two layers of phospholipids. | Lipid Bilayer |
| A system of membrane that in the a cell's cytoplasm and that assits in the production of lipids. | Endoplasmic Reticulum |
| A small cavity or sac that contains materials in a eukaryotic cell; forms when part of the cell membrane surrounds the materials to be taken into the cell or transported within the cell. | Vesicle |
| Cell organelle that helps make and package materials to be transported out of the cell. | Golgi Apparatus |
| A cell organelle that contains digestive enzymes. | Lysosmoe |
| In eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of celluar respiration, which produces ATP. | Mitochondrion |
| An organelle found in plant and algae cells where photosynthesis occurs. | Chloroplast |
| A large cavity or sac that is found in plant cells or protozoans and that contains air or partially digested food | Central Vacuole |
