Another way to prevent getting this page in the future is to use Privacy Pass. the vascular bundles of xylem that enable water to move up into the celery. That new empty space inside the leaves creates a low pressure, and like a drinking straw, this low pressure allows water below the leaf to travel up the stem. Phloem vessels: tubes that carry sap. Cross section of celery stalks after their long drink.

Add eight to ten drops of red food coloring to the water in the glass. A. Dermal tissue B. Cork: protective covering of the stem. Collenchyma, plant support tissue composed of living elongated cells with irregular cell walls that are able to extend and can thus accommodate growing tissues, such as stems and leaves, and form the chief supporting tissue in herbaceous plants. Introduction Stems contain the plant’s internal transport system. — into the glasses and stirred with a piece of celery, which was left in the glass.
