Cell organelles
Cell Organelles and their functiopn
| Question | Answer |
|---|---|
| the control center that contains the cell’s genetic material (DNA) and regulates its activities | Nucleus |
| the “powerhouses” of the cell —they generate most of the cell’s supply of adenosine triphosphate (ATP), which is used as a source of chemical energy | mitochondria |
| there are the protein factories of the cell. They are responsible for synthesizing proteins based on the instructions in messenger RNA | Ribosomes |
| a network of membranes that acts as transport system | endoplasmic reticulum |
| often called the post office of the cell, it modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles | Golgi apparatus |
| these “garbage disposals “ contain digestive enzymes to break down work-out organelles, cellular debris , and foreign materials | lysosomes |
| membrane-bound sacs that can be used for storage of water, nutrients, and wast e products. They are particularly large and central in plant cells. | Vacuoles |
| found in operant cells, there organelles are the sites of photosynthesis, where light energy is converted into chemical energy in the form of glucose | Choloroplasts |
