Study Notes
Cell Membrane
- The cell membrane is the outermost layer of the cell, acting as a protective barrier
- It is selectively permeable, controlling what enters and exits the cell, and facilitating communication between the cell and its environment.
- The cell membrane also allows the cell to respond to changes in its surroundings and helps cells recognize each other
Cytoplasm
- The cytoplasm is the gel-like substance that fills the cell and holds all the cell's organelles.
Nucleus
- The nucleus is the control center of the cell containing DNA, the genetic material that directs all cell activities.
- The nucleolus, found within the nucleus, is responsible for producing ribosomes.
Mitochondria
- Mitochondria are known as the "powerhouses" of the cell.
- They are responsible for converting food into energy in the form of ATP through cellular respiration.
Endoplasmic Reticulum
- The endoplasmic reticulum is a network of membranes that serves as a transport system within the cell.
- Smooth Endoplasmic Reticulum: Plays a key role in lipid synthesis, carbohydrate and steroid production, calcium regulation, and detoxification of harmful substances.
- Rough Endoplasmic Reticulum: Is studded with ribosomes and is essential for protein synthesis and polypeptide production.
Golgi Apparatus
- The Golgi apparatus acts as the cell's packaging and distribution center.
- Proteins synthesized by the cell are processed and packaged into vesicles for transport to other parts of the cell or for secretion outside the cell.
Ribosomes
- Ribosomes are the sites of protein synthesis.
- They interpret the genetic code from the DNA in the nucleus and use this information to assemble amino acids into proteins.
