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.
The root system is below ground. This system includes roots, tubers (an enlarged, fleshy, underground stem with buds capable of producing new plants) and rhizomes (a horizontal stem that is usually underground and roots grow from it.) Roots anchor the plant in soil so that it doesnât fall over. Root are much like straws through which water and minerals from the soil move upward to the shoot system. Tiny root hairs stick out of the root, helping in the absorption. Roots also store extra food for future use.
