Explain why cells are so small and why they are triggered to divide. (1 bonus point)

To answer this question we have to understand that, in order to survive, cells must constantly interact with their surrounding environment.

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.

Can you include the paragraph too ?

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
