Water passes from the soil into the roots by a physical process called
Detailed Explanation:
Water moves from soil into plant roots through osmosis, a process where water molecules pass through a semi-permeable membrane (root cell walls) from a region of higher water concentration (soil) to lower water concentration (root cells).
Diffusion involves movement of particles from high to low concentration but does not require a semi-permeable membrane. Absorption is a general term for uptake, while transpiration is water loss from leaves through stomata—not water uptake.
Therefore, osmosis is the specific physical process for water uptake by roots, making Option 4 the correct answer.
