Explanation

In the apoplast pathway (apoplastic route), water moves through the spaces between the cells and in the cell walls themselves.

Explanation

The mass of the proton divided by the mass of the electron is equal to 1836.

Therefore, the mass of the proton is 1836 times larger than the mass of the electron
