A set of term/definition flash cards to help me MASTER the concept of cells!
| Term | Definition |
|---|---|
| Cell Theory | A major theory of life science: the cell is the basic unit of life; organisms are made up of one or more cells; and all cells come from other cells. |
| Cell Membrane | The selectively permeable outer boundary of a cell that allows food and oxygen into the cell and wastes to leave it. |
| Nucleaus | The structure inside a cell that directs the cell activities, contains chromatin, and chromosomes in a dividing cell. |
| Chromatin | Hereditary material in a cell's nucleus; chromatin coils into the form of chromosomes when a cell divides. |
| Chromosome | Threadlike strands of DNA and protein in a cell nucleus that carry the code for the cell characteristics of an organism. |
| Cytoplasm | The gel-like substance inside the cell membrane that contains structures that carry out life processes. |
| Organelle | In eukaryotic cells, the structures within the cytoplasm that break down food, move wastes, and store material. |
| Endoplasmic Reticulum | A cell organelle consisting of folding membranes that moves materials around within the cell. |
| Ribosome | A cell organelle on which a protein is made. |
| Golgi Bodies | Cell organelles consisting of stacks of membrane-covered sacs that package and move proteins to the outside of the cell. |
| Mitochondria | Cell organelles that break down food molecules and release energy. |
| Lysosome | A cytoplasmic organelle that contains chemicals and digests wastes and worn out cell parts. |
| Cell Wall | In plants, the rigid structure is made of cellulose that surrounds a plant cell membrane and supports and protects it. |
| Chloroplast | Plant cell organelles in which light energy is changed into chemical energy in the form of sugar during the process of photosynthesis. |
| Tissue | Groups of similar cells that do the same sort of work. |
| Organ | A structure made up of different types of tissues that work together to do a specific job. |
