In the experiment of observing xylem in celery, food coloring travels up the celery due to a process called capillary action. Capillary action occurs as a result of cohesion and adhesion of water molecules. The water molecules in the xylem vessels of the celery are attracted to each other (cohesion) and are also attracted to the walls of the xylem vessel (adhesion).
When the bottom of the celery stalk is placed in water containing food coloring, the water molecules are drawn up into the xylem vessels through capillary action. As water evaporates from the leaves of the celery, more water molecules are pulled up through the xylem vessels, bringing the food coloring along with them. This movement of water and food coloring through the xylem is known as transpiration.

can you explain capillary action in a more simpler term
Certainly! Capillary action is the ability of a liquid, such as water, to move up against the force of gravity in a narrow space, like a small tube or a narrow opening. This occurs because of two important factors: cohesion and adhesion.
Cohesion refers to the attraction between molecules of the same substance. In the case of water, the water molecules are attracted to each other. Adhesion, on the other hand, refers to the attraction between different substances. In relation to capillary action, water molecules are attracted to the walls of a narrow tube or vessel.
When water is in a narrow space, such as the xylem vessels in celery, cohesion causes the water molecules to stick together. This cohesion, combined with adhesion to the walls of the vessel, allows the water to climb up the walls. As a result, the food coloring, which is dissolved in the water, is pulled up with it.
In simpler terms, capillary action is like a "tug-of-war" between the water molecules and the walls of a narrow space. The cohesive forces among the water molecules, along with their adhesion to the vessel's walls, work together to pull the water (and anything dissolved in it) upwards, defying gravity.

why does food colouring travel up the celery
answer in the simplest form
The food coloring travels up the celery because the water in the celery's xylem vessels pulls it up through a process called capillary action.
could you add better vocabulary
Certainly! The food coloring travels up the celery because of the process known as capillary action. Capillary action occurs due to the cohesive and adhesive properties of water.
Cohesion refers to the attraction between water molecules, causing them to stick together. Adhesion, on the other hand, refers to the attraction between water molecules and the walls of the xylem vessels.
When the celery is placed in water containing food coloring, the water molecules are pulled up into the xylem vessels of the celery through capillary action. This happens because the cohesive forces between water molecules allow them to transfer the pulling force from the lower parts of the celery to the upper parts. As a result, the food coloring is carried along with the water and travels up the celery.

simpler but with better vocabulary
Sure! The food coloring travels up the celery because of a phenomenon called capillary action. Capillary action occurs due to the cohesive and adhesive nature of water.
Cohesion refers to the water molecules sticking together, like a team, thanks to their attractive forces. Adhesion, on the other hand, is the attraction between water molecules and the walls of the celery's xylem vessels.
When the celery is placed in water with food coloring, the water molecules are drawn up into the celery's xylem vessels through capillary action. The cohesive forces between the water molecules help them create a chain-like "tug," pulling the water and food coloring up through the narrow vessels. This upward movement is possible because of the water's adhesive attraction to the vessel walls. As a result, the food coloring travels up the celery along with the water.
