Study Notes
Relative Sizes of Cellular Structures
- Animal cells are typically 10-100 µm in diameter.
- Plant cells are typically 10-100 µm in length.
- Nuclei are typically 3-10 µm in diameter.
- Mitochondria are typically 1-2 µm long.
- Chloroplasts are typically about 5 µm long.
- Ribosomes are typically 20-30 nanometers in diameter.
When to Use Estimations
- Estimations are helpful for quickly determining cell type (animal or plant), comparing organelle sizes, and identifying abnormally large or small structures.
- Remember that cell sizes can vary, and estimations are general ranges. Precise measurements may be needed for more accurate scientific work.
