Students are instructed to place leafy celery stalks into color water in a beaker overnight. The following day, the students observed the color of the celery leaves changed from green to red. The students cut across the edge of the celery and observed the small tube openings along the edge are also red.
How do the plant systems work together to make the movement of the liquid possible?
The roots absorb the water, minerals move up the stem, while the stem moves food produced in the leaves down to the roots.
The roots anchor the plant into the soil and the stem holds the leaves up.
The roots absorb their own water and minerals and the leaves push out CO2.
The roots lose water vapor to the soil and the stem loses water vapor through the leaves.
