| Definition | Term |
|---|---|
| A double layer of phospholipids that forms a boundary between a cell and the surrounding environment and controls the passage of materials into and out of a cell. | cell membrane |
| Rigid structure that gives protection, support, and shape to cells in plants, algae, fungi and bacteria. | cell wall. |
| Flagella are long, threadlike appendages on the surface of a living cell. | Flagella |
| Cilia are short, hair like appendages extending from the surface of a living cell. | cilia |
| a small, double-membraned organelle of plant cells and certain protists, occurring in several varieties, as the chloroplast, and containing ribosomes, prokaryotic DNA, and, often, pigment | plastid |
| takes up and processes secretory and synthetic products from the endoplasmic reticulum and then either releases the finished products into various parts of the cell cytoplasm or secreted them to the outside of the cell. | golgi apparatus |
| a shifting lattice arrangement of structural and contractile components distributed throughout the cell cytoplasm, composed of microtubules,microfilaments, and larger filaments, functioning as a structural support and transport mechanism. | cytoskeleton |
| divides in perpendicular fashion during mitosis, the new pair of centrioles moving ahead of the spindle to opposite poles of the cell as the cell divides. | centrioles |
| Bean shaped organelle that supplies energy to the cell and has its own ribosomes and DNA | mitochondrion |
| Organelle composed of numerous membranes that are used to convert solar energy into chemical energy, contains chlorophyll. | chloroplast |
| An organelle composed of a double membrane that acts as the storehouse for most of a cell’s DNA. | nucleus. |
| a conspicuous, rounded body within the nucleus of a cell. | nucleolus |
| series of connected flattened sacs. It plays a central role in the synthesis and export of proteins and glycoproteins and is best studied in the secretory cells | Rough E.R. |
| associated with the production and metabolism of fats and steroid hormones. | smooth E.R. |
| Organelles that links amino acids together to form proteins. | ribosome |
| Organelle that contains enzymes. | lysosome |
| Organelle that is used to store materials, such as water, food, or enzymes, that are needed by the cell. | vacuole |
| small organelle that contains and transports materials within the cytoplasm. | vesicle |
| Membrane bound structure that is specialized to perform a distinct process within a cell. | organelle |
| An organelle composed of a double membrane that acts as the storehouse for most of a cell’s DNA. | nucleus. |
| Composed of several or many cells. | multicullular |
| an organism that consists of only one cell. | single-celled |
