@jmtoni, Cardboard palms will form a trunk, partially above ground and partially below. They then will make offsets to form multi-headed trunks. I'm not sure if yours is forming an offset at this young age or if it is two actual plants from multiple seeds being started in the same pot. You can divide them, but I would wait until at least spring to do so. Then be careful of overwatering until you see active growth.
Yours currently has the juvenile foliage. It will develop foliage more like the pics Tarev posted as it matures. What you are calling a "root" is the head of the little baby trunks. These grow differently than other trees that you can cut back to make them branch. With cycads such as this Zamia, if you cut or damage the head you may very likely end up killing it. The parts that you have circled are where the "whirls" of fronds emerge from, and in this case, the protrusions in your circles are the newest fronds that have come out. At this young age, yours is only producing one frond per whirl. As your plant matures and grows, it will produce more and more fronds in each new whirl.
