Study Notes
Cell Biology
- The basic membrane-bound unit in biology is a cell.
- A single cell can be an organism, as seen in unicellular organisms.
- The smallest known cells, typically mycoplasmas, have a size range of 0.1-1.0 μm in diameter.
- The mass of the smallest known cells is approximately 10^-14 grams.
- As an individual unit, a cell can grow, respond to stimuli, reproduce, metabolize, maintain homeostasis, and adapt to environment.
