Study Notes
Cell Characteristics
- Living cells differ from non-living cells due to distinct characteristics
- Organelle shown in the figure: Mitochondrion, function: generate energy for the cell
Cell Types
- Prokaryotic cells distinguished from eukaryotic cells by the absence of a true nucleus
- Dendritic cells have a long, branched structure, requiring many connections with neighboring cells
Nucleus Function
- Nucleus: main function is to store genetic information
Cellular Processes
- Exocytosis: process by which vesicles are secreted from cells
Cell Component Identification
- Rough Endoplasmic Reticulum (RER): indicated by the line labeled "3" (green)
Mitochondrial Structure
- Inner mitochondrial membrane: appears folded and cristae-like when examined with transmission electron microscopy
Prokaryotes
- Archaea and Bacteria: both prokaryotes, distinguished by different membrane lipids and metabolic processes
Common Traits
- All living cells: share common characteristics that distinguish them from non-living cells
