Of these, more than 260,000 are seed plants. Mosses, ferns, conifers, and flowering plants are all members of the plant kingdom. Some biologists also consider green algae to be plants, although many others exclude all algae from the plant kingdom and place them in Protista.

In the half of the bundle that faces the exterior is the phloem, which contains sieve tube elements and their accompanying companion cells. In the above of the vascular bundle on the left, label the xylem, phloem, a vessel element, sieve tube element, and companion cell.

Dicots, exemplified by the basswood tree, have three main stem areas: bark for protection, cortex for food storage, and cambium for producing new xylem and phloem. Xylem supports the plant and transports water and minerals.
