The ports on your router are already switch ports. If they weren't, they'd have IP addresses associated with them. DHCP has nothing to do with routers or router functionality, it is included as an added feature. You can turn it off and the device is still a router.
The plant root system constitutes the major part of the plant body, both in terms of function and bulk. In terrestrial plants, the root system is the subterranean or underground part of the plant body while the shoot is the aboveground part. Roots are branching organs which grow downward into the soil, a manifestation of geotropism. Branching occurs irregularly and not from nodes as in stems.
Plant Parts-Stems. Stems carry water and nutrients taken up by the roots to the leaves. Then the food produced by the leaves moves to other parts of the plant. The cells that do this work are called the xylem cells.They move water. The phloem cells move the food.Stems also provide support for the plant allowing the leaves to reach the sunlight that they need to produce food.lant Parts-Stems.
