Study Notes
Cell Membrane
- A thin layer of lipids and proteins surrounding the cell, serving as a barrier between the cell and its surroundings.
- Primary role is to protect the cell from its environment.
- Acts as a semi-permeable or selectively permeable membrane, controlling the entry and exit of nutrients and microscopic entities into the cell.
Nucleus
- An organelle comprising several sub-organelles: nucleolus, nucleus envelope, and chromatins.
- Contains DNA and other genetic materials.
Learn about the cell membrane and nucleus, their functions and components. Understand the role of cell membranes in protecting the cell and controlling the entry and exit of nutrients.
