This is a picture of a celery stalk. A celery stalk is an example of phloem. Phloem is the tissues of vascular plants that conducts the sugars produced by photosynthesis to all parts of the plant. Phloem consists of the cells; sieve elements, parenchyma cells, sclereids, and fibers. This picture is the cross section of a celery stalk which contain the tissues phloem and xylem. While phloem transports the foods (sugars), xylem transports water and other nutrients throughout the plant.
