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 primary root - the original seedling root. It becomes the taproot of the plant root system.The fibrous root system...thin lateral roots (as in the grass) thick function as feeder roots. Root Modifications -Roots swollen and fleshy with stored food in the form of starches and sugars.
