Definition
| a basic unit of structure and function in all organisms |
|
|
Term
|
Definition
| states that all organisms are made up of one or more cells, the cell is the basic unit of life, and all cells come from other cells |
|
|
Term
|
Definition
| an organism whose cells have a distinct membrane bound nucleus and organelle |
|
|
Term
|
Definition
| composed of more than one cell |
|
|
Term
|
Definition
| structure in the cytoplasm of a eukaryotic cell that can act as a sstorage site, process energy, move materials, or manufacture substances. |
|
|
Term
|
Definition
| a unicellular organusm that lacks a true nucleus and membrane organelle |
|
|
Term
|
Definition
| composed of only one cell |
|
|
Term
|
Definition
| protective outer covering of all cells that regulates the interaction between the cell and its environment by allowing materials into and out of the cell. Semi-permeable membrane (like a screen door) |
|
|
Term
|
Definition
| rigid outermost layer that encloses, supports, and protects the cells of plants, algae, fungi, and most bacteria (like a door) |
|
|
Term
|
Definition
| constantly moving jello like mixture inside the cell membrane; the location of most of a cells organelles and their activities |
|
|
Term
|
Definition
| organelle that controls all the activities of a cell and contains hereditary material made of proteins and DNA (the brain) |
|
|
Term
|
Definition
| (also called a nuclear envelope) layer of two membranes that surrounds the nucleus of a cell and regulates the movement of materials into and out of the nucleus (like a screen door for nucleus) |
|
|
Term
|
Definition
| small, dense region within most nuclei in which the assembly of ribosomes (proteins) begins |
|
|
Term
|
Definition
| small structures on which cells make their own proteins |
|
|
Term
|
Definition
| green, chlorophyll containing, plant cell organelle that uses light energy to produce sugar from carbon dioxide and water (photosynthesis) |
|
|
Term
|
Definition
| the green pigment in plants that is necessary for the production of plant food by photosynthesis |
|
|
Term
|
Definition
| organelle where energy is released from broken-down food molecules. Power plant of the cell. About the size of bacteria (power houses of the cell) |
|
|
Term
| endoplasmic reticulum (E. R.) |
|
Definition
| organelle that moves materials around in a cell and is made up of a complex series of folded membranes. Can be rough (with attached ribosomes) or smooth (without attached ribosomes) |
|
|
Term
|
Definition
| flattened membranes that package cellular materials and transport them within the cell or out of the cell (like UPS) |
|
|
Term
|
Definition
| cell organelle that stores materials such as water, waste products, salts, proteins, and carbohydrates. Larger in plant cells than in animal cells. Vescicles have similar functions |
|
|
Term
|
Definition
| network of protein filaments within some ells that helps the cell maintain its shape and is involved in many forms of cell movement |
|
|
Term
|
Definition
| cell organelle that contains enzymes to break down food molecules, cell wastes, worn-out cell parts and invading viruses and bacteria (like Lysol) |
|
|
Term
|
Definition
| two structures in the cytoplasm located near the nuclear membrane that help in cellular reproduction. |
|
|
Term
|
Definition
| contain complex chemical information that directs the cell's hereditary-related activities (DNA) |
|
|
Term
|
Definition
| located inside the nucleus. The blueprints for a cell, containing the genetic instructions used in the development and functioning of all living things |
|
|
Term
|
Definition
| a series of events that cells go through as they grow and divide. During a cell cycle the cell grows, replicates its DNA, prepares for division, and divides to form two daughter cells, each of which then begins the cycle again. |
|
|
Term
|
Definition
| form of asexual reproduction in which a new genetically identical organism (bud) forms on the side to parent then breaks off |
|
