How would you compare the rate of uptake of the coloured solution by the plant (you know in this experiment when they put a plant into coloured water, to observe how the water travels up the plant), with another plant that has had its roots cut off?

take same species and age of plant. then cut off the root of one plant then place both plants in the same amount of dye. then measure initial volume then later measure the final volume of both of the plants.

nid404:
shogun u missed 1 point. keep the plants for the same time in the water and let all other external conditions be same.
