Although it is generally the case that biological cells are too small to be seen at all without a microscope, there are exceptions as well as considerable range in the sizes of various cell types. Eukaryotic cells are typically 10 times the size of prokaryotic cells (these cell types are discussed in the next Chapter). Plant cells are on average some of the largest cells, probably because in many plant cells the inside is mostly a water filled vacuole.

So, you ask, what are the relative sizes of biological molecules and cells? The following are all approximations:

0.1 nm (nanometer) diameter of a hydrogen atom

0.8 nm Amino Acid

  2 nm Diameter of a DNA Alpha helix

  4 nm Globular Protein

  6 nm microfilaments

 7 nm thickness cell membranes

 20 nm Ribosome

 25 nm Microtubule

 30 nm Small virus (Picornaviruses)

 30 nm Rhinoviruses

 50 nm Nuclear pore

100 nm HIV

120 nm Large virus (Orthomyxoviruses, includes influenza virus)

150-250 nm Very large virus (Rhabdoviruses, Paramyxoviruses)

150-250 nm small bacteria such as Mycoplasma

200 nm Centriole

200 nm (200 to 500 nm) Lysosomes

200 nm (200 to 500 nm) Peroxisomes

800 nm giant virus Mimivirus

  1 µm (micrometer)

       (1 - 10 µm) the general sizes for Prokaryotes

  1 µm Diameter of human nerve cell process

  2 µm E.coli - a bacterium

  3 µm Mitochondrion

  5 µm length of chloroplast

  6 µm (3 - 10 micrometers) the Nucleus

  9 µm Human red blood cell

 10 µm

       (10 - 30 µm) Most Eukaryotic animal cells

       (10 - 100 µm) Most Eukaryotic plant cells

 90 µm small Amoeba

100 µm Human Egg

up to 160 µm Megakaryocyte

up to 500 µm  giant bacterium Thiomargarita

up to 800 µm  large Amoeba

  1 mm (1 millimeter, 1/10th cm)

  1 mm Diameter of the squid giant nerve cell

up to 40mm Diameter of giant amoeba Gromia Sphaerica

  120 mm Diameter of an ostrich egg (a dinosaur egg was much larger)

  3 meters Length of a nerve cell of giraffe's neck

Next to the next Megakaryocyte is a Amoeba

What limits cell sizes?

Prokaryotes - Limited by efficient metabolism

Animal Cells (Eukaryotic) - Limited by Surface Area to Volume ratio

Plant Cells (Eukaryotic) - Have large sizes due to large central vacuole which is responsible for their growth
