A nucleus is generally 10 to 20 micrometers in diameter. However, in humans, nuclei are only 6 micrometers in diameter on average. Mitochondria are approximately 1 micrometer in length. Chloroplasts can be up to 10 micrometers long and 0.5 to 2 micrometers thick. However, they do vary in shape and size in different types of cells. Lodish, H. et al.
