Cells Test
| Term | Definition |
|---|---|
| CELL MEMBRANE | ~Outer covering of animal cells ~Just under the cell wall in plant cell ~Semi Permeable: Controls movement of materials in and out of the cell |
| CYTOPLASM | ~Clear, thick, jelly-like substance ~Organelles are found within the cytoplasm |
| NUCLEUS | ~The control center of the cell ~Regulate all activities of the cell ~Nucleolus and Chromosomes are found inside the nucleus ~Chromosomes are the compacted form of DNA |
| RIBOSOMES | ~Makes protein |
| MITOCHONDRIA | ~“Powerhouse” of the cell ~Makes energy! |
| ENDOPLASMIC RETICULUM (ROUGH OR SMOOTH) | ~Transportation system - carries proteins that are made in the ~nucleus from inside the cell to outside the cell ~Rough = Ribosomes |
| GOLGI BODIES | ~Various molecules are manufactured and packaged for export from the cell. |
| VACUOLES | ~Plant cells usually have 1 large vacuole ~Animals may have a few small ones, if any. ~Stores water for the cell |
| LYSOSOMES (only Animal cells) | ~Contains enzyme which break down large food molecules and old cell parts. New parts can be made again (Enzymes - molecules that speed up a chemical reaction) |
| CYTOSKELETON | ~Provide shape for animal and plant cell **For cell project, only need to show this for the animal |
| CELL WALL | ~Found in plant cells ONLY ~Provides support and protection Strong |
| CHLOROPLAST | *PLANTS ONLY* ~Food producing organelles ~Captures sunlight which then can be used during photosynthesis ~Green due to chlorophyll |
| NUCLEOLUS | ~Makes ribosomes |
| ORGANELLES | ~Structures within the cell that work together for the cell to function ORGANELLES → CELLS→ TISSUES → ORGANS → ORGAN SYSTEMS → ORGANISM |
