Detailed explanation-1: -Celery is handy for demonstrating capillary action because it has a lot of xylem tubes in the stalk, making for fast water uptake. You’ll see the pale green leaves take on a reddish and bluish colour because the dissolved food colouring moves with the water through the xylem tubes into the celery stalk and leaves.

Detailed explanation-2: -The science bit – how plants transport water The experiment with a stick of celery reveals that this happens through special tubes, called xylems, which take up the food colouring. The process is accelerated by evaporation from the celery leaves and you can make it go even faster by using a hairdryer on the leaves.

Detailed explanation-3: -By the process of capillary action! We can see this in action with the celery. The cut celery stalks take up colored water through their stem and the colored water moves from the stem to the leaves. Water travels up tiny tubes in the plant via the process of capillary action.
