A pupil accidentally "watered" a potted plant with concentrated salt solution after sometime the plant began to wilt.
The wilting of the plant is due to the fact that
the root hair die off and can no longer absorb water
the salt solution causes faster rate of transpiration leading to the death of the plant cell
the salt solution has caused water lost from the plant cell leading to loss of turgor
the plant tissue has been poisoned by the salt which is absorbed by the plant
