Final answer:
Leaving some original soil around the roots when moving a plant is important because it provides beneficial microorganisms, protects the roots, and helps the plant establish itself in its new location.
Step-by-step explanation:
When moving a plant from one place to another, it is important to leave some original soil around the roots. This is because the original soil contains beneficial microorganisms that help the plant absorb nutrients and water. Additionally, the original soil acts as a protective layer around the roots, preventing damage during the transplantation process. Leaving some original soil also helps the plant to establish itself more quickly in its new location.
