why do plants do well sitting with their roots in just water, but once you’ve planted them they start to rot if the soil is too wet?

Question

why do plants do well sitting with their roots in just water, but once you’ve planted them they start to rot if the soil is too wet?

In: Biology

Answer 1

* when roots are submerged in a lot of water, there is sufficient oxygen in the water for them to absorb…in soil, the oxygen in the water is quickly used up and the deoxygenated water blocks the air
* rot is often caused by mold, which requires both water and nutrients from soil…no soil, no mold
