Cell Theory and Structure
| Question | Answer |
|---|---|
| The theory that the cell is the fundamental structural and functional unit of living matter. | Cell Theory |
| the thin membrane that surrounds the cytoplasm of a cell; regulates the passage of materials in and out of the cell. | Cell Membrane |
| Surrounds a cell membrane of a plant cell to give structure and protection to the cell.(provides support). | Cell Wall |
| The green organelle in plant cells that converts light energy into chemical energy. | Chloroplast |
| Found in the nucleus and made of DNA, these contain the genetic information of the cell. | Chromosomes |
| Hair-like structures that extend from the surface of the cell to help with movement. | Cilia |
| The jellylike material that fills the cell, and in eukaryotic cells, surrounds the nucleus. | Cytoplasm |
| Long, whip like structure that allows a cell to move. | Flagellum |
| Holds waste materials from the cell; breaks down food, worn out pieces of cells, and other wastes. Generally found in animal cells. | Lysosomes |
| Functions in energy production, the powerhouse of the cell. | Mitochondrion |
| Found in eukaryotic cells; contains genetic material (DNA) responsible for controlling the activities of the cell. | Nucleus |
| Stores water and food in both plant and animal cells (larger in plants). | Vacuole |
| How the parts are put together. | Structures |
| Tube-like structures that exist in pairs in animal cells; guide the chromosomes during cell division. | Centriole |
| Building site for the proteins of the cell | Ribosomes |
| Clear tubular passageways studded with ribosomes; for transportation of materials throughout the cell . | Endoplasmic Reticulum- Rough |
| clear tubular passageways (free of ribosomes); for transportation of materials throughout the cell. | Endoplasmic Reticulum- Smooth |
| stores packages and ships cellular materials. | Golgi Bodies |
