Study Notes
Cellular differences
- Living cells differ from non-living cells in their structural and functional properties
- Organelle function: mitochondria generate energy for the cell through cellular respiration
- Prokaryotic cells lack a true nucleus, whereas eukaryotic cells have a membrane-bound nucleus
Cellular structure
- Dendritic cells have a long, branched structure requiring multiple connections with neighboring cells
- The nucleus is responsible for storing genetic information and regulating gene expression
- Vesicle secretion from cells is a process called exocytosis
Mitochondrial structure
- The inner mitochondrial membrane appears cristae-like when examined with transmission electron microscopy
- The inner membrane is highly folded to increase surface area for energy production
Prokaryotes
- Archaea and bacteria are both prokaryotes, but they differ in their cell wall composition, metabolism, and environmental adaptations
Universal cellular properties
- All living cells possess the ability to grow, reproduce, respond to stimuli, and maintain homeostasis
