Study Notes
- Cells have a membrane to keep their contents separate from the outside environment
- Big and complex cells, even from multicellular organism need many chemical activities to keep their complicated structure and working order
- Cells use membrane-bound structures (called organelles) inside themselves to keep the different chemical activities separate.
- Eukaryotic cells use organelles, while prokaryotic cells do not
- Some organelles can only be seen using an electron microscope.
- Examples of cell organelles:
- Endoplasmic reticulum
- Golgi apparatus
- Lysosomes
- Mitochondria
- Plastids
- Organelles carry out crucial functions in cells.
