Study Notes
Cell Structure and Function
- The organelle that surrounds the nucleus and supports and protects the cell is the cell membrane.
Nuclear Structure
- The nuclear membrane surrounds the nucleus and has pores that allow molecules to pass through.
- The DNA is located in the nucleus of a cell.
Ribosomes and Protein Synthesis
- The nucleolus, which is located in the nucleus, makes ribosomes.
- Ribosomes are responsible for protein synthesis in a cell.
- Ribosomes can be found throughout the cell, either freely floating or attached to the Rough Endoplasmic Reticulum.
- The function of ribosomes is to translate mRNA into a polypeptide chain.
Endoplasmic Reticulum
- The Rough Endoplasmic Reticulum is distinguished from the Smooth Endoplasmic Reticulum by the presence of ribosomes attached to its surface.
- The Rough Endoplasmic Reticulum is involved in protein synthesis and transport.
Cell Membrane
- The cell membrane is responsible for protecting and supporting the cell, and is semi-permeable, allowing certain molecules to pass through.
- The cell membrane and the nuclear membrane are distinct and separate structures.
- The cell membrane shares the function of protecting and supporting the cell with the cell wall (in plant cells) or the periplasmic space (in bacterial cells).
