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.
Root, in botany, that part of a plant normally underground. Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods. play_circle_outline.
