Study Notes
Cell Components & Functions
- All organisms use carbohydrates, proteins, lipids, and nucleic acids.
- Instructions for growth, reproduction, and development are encoded in DNA.
Cell Structure and Support
- The cell wall and cell membrane provide support and structure to the organism.
Meiosis
- Meiosis causes daughter cells to be genetically different from parent cells.
Cell Lifespans
- Normal cells in the body age and die.
- White blood cells live for about 13 days.
- Red blood cells live for about 120 days.
- Liver cells can live up to 18 months.
- Brain cells can live a person's entire lifetime.
Cell Apoptosis
- Cell apoptosis is a gentle and controlled process that does not damage neighboring cells.
Homeostasis
- Homeostasis is the balance of two important cellular processes.
