Many of us tend to view water as a liquid rather than a floating structure
Water is not a liquid; water is an air, or a fluid, and the two properties are related, yet completely contradictory. Whilst water should flow normally through channels of water solids, in most cases, water will not do so. Not only that, but in many instances, water moves much more quickly in a liquid than a solid.
And yet, the nature of our water shows how fluid it really is. Most of us tend to view water as a liquid rather than a floating structure, it has a tendency to float or detach from its moorings when water is in hot or high pressure environments.
So how do we grow pothos trees in water?
When you consider the pothos tree, it is no surprise that it is more closely related to the ground. Its roots are mostly composed of water droplets that fall off onto the hard, porous soil. This droplet-falling system is similar to that of the root system of any fungus, such as the roots of fungi in which a specific fungus produces droplets that fall onto the soil in an attempt to nourish its leaves, before being collected. The droplets of water, gathered by the fungi, pass to the primary stem (fungus stems).
Some types of fungus are already adapted to grow at the top of the soil surface, this includes the root of such fungus as ‘glacial thistle’. This fungus, named after the glacier of which it is an adaptation, grew taller than most of the other plants in a number of locations in the Alps. Over time, thistle was able to grow its way up the sides of the glaciers to grow in more sheltered and warmer environments. It was this ability to grow in the scarcest and coldest places that led scientists to suggest that other species of fungi may possess similar abilities.
Indeed, some species of fungi are capable of growing above the soil surface, and these fungi have even been known to grow well on the surface of concrete.
The root system of the pothos tree is not very unusual to a botanist, as their roots do not actually exist under the soil surface, they are typically shallow and float in the water. They grow in shallow water that is exposed to the sun or floods, whilst it is often prone to frosts. To harvest the seeds, however, they need to actively expand the root mass.
