Cell Structure
| Question | Answer |
|---|---|
| a phospholipid layer that covers a cell's surface and acts as a barrier between the inside of a cell and the cell's environment | cell membrane |
| an organelle found in plants and algae cells where photosynthesis occurs | chloroplast |
| a collection of genetically identical cells that are permanently associated but in which little or no integration of cell activities occurs | colonial organism |
| the region of the cell within the membrane | cytoplasm |
| 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 |
| an organism made up of cells that have a nucleus and membrane-bound organelles | eukaryote |
| a long, hairlike structure that grows out of a cell and enables the cell to move | flagellum |
| a cell organelle that helps make and package materials to be transported out of the cell | golgi body, golgi apparatus |
| in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration | mitochondrion |
| in a eukaryotic cell, a membrane-bound organelle that contains the cell's DNA | nucleus |
| a group of organs that work together to perform body functions | organ system |
| a collection of tissues that carry out a specialized function of the body | organ |
| 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 single-celled organism that does not have a nucleus or membrane-bound organelles | prokaryote |
| a cell organelle where protein synthesis occurs | ribosome |
| a group of similar cells that perform a common function | tissue |
| a fluid-filled vesicle found in the cytoplasm of plant cells or protists | vacuole |
| a small cavity or sac that contains materials in a eukaryotic cell | vesicle |
