The importance of the control of movement in cells and organisms

Hi,
One type of movement is that of substances including by diffusion.
Look at this answer of mine to a slightly different Q, then add to it/adapt your answer as needed, yeah? Make sure you stress "control".

ADDITIONS:
1. Other methods of movement of substances - osmosis, active transport, facilitated diffusion, etc;
2. movement of cells of immunity to site of infection/injury e.g. leukocytes for phagocytosis.
3. Movement of structures of organisms - pseudopodia; tail of spermatozoa; cilia in trachea/nose; tongue to mix saliva with food for efficient digestion; rugae of stomach.
4. Movement of parts of body: muscles on bones - control by cerebellum and basal ganglia; proprioceptors in muscles/joints; co-ordination of external ocular muscles to not get diplopia [double vision] [is it not a miracle that e.g. if we look left, the left eye moves outwards but the right inwards, yet exactly in tandem? - oc feat of nature!]
5. Movement of whole animal/plant: locomotion; phototaxis; geotaxis, etc.

REMEMBER: for all these points, keep repeating the word "control", with me? What counts is mark - mark - mark; every single mark is like a goal in hockey - the end result depends on it!

Good luck & be safe!
