Question | Answer |
---|---|
a microscope that uses a beam of visable light passing through one or more lenses to magnify an object. | Light Micrscope |
a microscope that focusses a beam of electrons to magnify objects. | Electron Microscope |
the increase of an objects apparent size by using lenses or mirrors. | Magnification |
in microscopes, the ability to form images with fine detail. | Resolution |
a microscope that produces an enlanged, three demensonal image of an object by using a beam of electrons 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 has a specific job, and that cells come only from existing cells. | Cell Theory |
A phospholipid layer that covers a cells surface and acts as a barrier between the inside of a cell and the cells enviroment. | Cell Membrane |
the region of the cell within the membrane that includes the fluid the cytoskeleton, and all of the nucleus. | Cytoplasm |
are the cellular structures on which proteins are made. | Ribosomes |
an organism that consist 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, hair like 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; eukaroytes includes animals, plants, and fung; but not bacteria or cyanobacteria. | Eukaroyte |
in a eukaryotic cell, biology, a membrane- bound organelle that contains the cells DNA and that has a role in processes such as growth, metabolism, and reproduction. | Nuclues |
one of the small bodies that are found in the cytoplasm of a cell and that are specialized to perform a specific function. | Organelle |
a hair like structure arranged in tighly packed rows that projects from the surface of some cells. | Cilium |
a lipid that contains phosphorus and that is a structional component in a call membrane | Phospholipid |
the basic structure of a biological membranes, composed of two layers of phospolipids. | Lipid Bilayer |
a system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins and 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 transported within the cell. | Vesicles |
cell organelle that helps make and package materials to be transported within the cell. | Golgi Appartus |
a cell organelle that contains digestive enzymes. | Lysosome |
in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of celluar respiration, which produces ATP. | Mitochondrian |
organelle found in plant and algae cell where photosythesis occur. | Chloroplast |
a large cavity or sac that is found in plant cells or protozoans and that contains air or partially digested food. | Central Vacuole |
