LE- The Cell
Cell organelles and their function
| Term | Definition |
|---|---|
| Prokaryotic | Lack membrane bound organelles |
| Eukaryotic | Membrane bound organelles |
| Organelles | Structures inside the cell |
| Cell Wall | Provides structure for the plant, made of cellulose. |
| Cell membrane | Selectively permeable-only allows certain materials to pass through, made of protein and lipids |
| Cytoplasm | Jelly like substance inside the cell, holds the organelles in place. |
| Endoplasmic Reticulum | Channel way throughout the cell and transports substances around the cell |
| Ribosome | Where protein synthesis takes place, near ER. |
| Nucleus | Control center of the cell.Controls reproduction and metabolism. Contains the nucleoli. Stores DNA |
| Nucleolus | Where ribosomes are produced |
| Golgi Bodies | Stacks of flattened membrane sacs, process, packaging and storage |
| Lysosome | Usually in animal cells. Has digestive enzymes to break down food and old organelles |
| Mitochondria | Energy production (ATP),surrounded by 2 membranes Where cellular respiration takes place. |
| Centrioles | Found near the nucleus, only in animal cells, involved in cell reproduction |
| Chloroplast | Where photosynthesis takes place, Has own DNA, Green pigment and in plants only |
| Vacuole | Storage for water and food, Large in plants, Small in animals |
| Microtubules | Found in the cytoplasm, gives cell shape |
| Microfilaments | Associated with cell movement |
| Chromosomes | Stores genetic information. Found inside the nucleus. |
