Cilia and flagella assist in the movement of cells. Not all cells have them, but they are very common in prokaryotic cells. They are usually long, and appear to be projections of the cell. Without them, some cells would be unable to function. For example, sperm cells require flagella to move towards the egg.
Proteins such as haemoglobin and myoglobin which require haem groups covalently bonded to the proximal histidine (HisF8) residue for O2 binding.
