Transport in Plants

Aim: To observe xylem tissue and prove that they transport water up the plant.

Equipment: One stick of celery with the leaves still attached, a retort stand, boss head and clamp, a petri dish, water, food colouring, a knife or scalpel.

Method:

1. Make a cut across the base of the celery stalk to expose a new section of the stem.
2. Fill the petri dish with water and add a few drops of food colouring.
3. Place the celery stalk in the petri dish and gently clamp it in a place using retort stand, boss head and clamp.
4. Leave the stalk undistributed for 24 hours.
5. Remove the stalk from the clamp and petri dish. Cut the stem about 1/3 of the way up the stem.
