Why is the root apical meristem covered by a thimble-shaped cap, whereas the shoot apical meristem is not?

Roots need protection as they push through the soil.

  

To respire, the shoot apical meristem cannot be covered.

  

Roots seek out water; shoots do not.

  

The root cap senses gravity, and shoot apical meristems do not need to sense gravity.
