An example of a process that involves osmosis is the

A.

movement of water from root hairs into cortical cell

B.

reabsorption of food nutrients from the kidney into blood capillaries

C.

translocation of starch from leaves to all parts of a plant

D.

movement of digested food from ileum into blood capillaries

Correct answer is A

Movement of water from root hairs into cortical cells involves osmosis. When a plant's roots absorb water from the soil, it passes through the root hairs and moves into the cortical cells (which are part of the root's inner layer) through osmosis. This osmotic movement of water helps maintain water balance and nutrient distribution within the plant.
