Question

Rank these structures from smallest to largest:

Please include the relative size/dimension of each

1. Mitochondria

2. Bacterial cell

3. Eukaryotic cell

4. Ribosome

5. Hemoglobin

6. Amino Acid

7. Water

8. Sucrose

Answer 1

Water———————————0.275 nm

Amino acid————————-0.8 nm

Sucrose—————————- approximately 3 nm

(but exact size is unknown, as the size of glucose is 1.5nm and fructose is pentose sugar so it is smaller than glucose. Sucrose is made up of glucose and fructose, so the average size of sucrose will not be more than 3nm)

Haemoglobin———————- approximately 4nm

Ribosome—————————20nm

Mitochondria———————3 µm

Prokaryotic cell——————- up to 10µm

Eukaryotic cell———————10 to 100µm
