Why would a very short root system be a harmful adaptation to desert cactus plants?

Answer 1

because long root systems dig deep into the ground where there is more water than near the surface, and if the root systems were shorter, then the cactus wouldn't be able to get the water that it needs to survive.

Answer 2

A short root system would limit the cactus's ability to access water from deep underground, which is crucial in arid environments. Without a deep-reaching root system, the cactus may struggle to survive during prolonged droughts and periods of limited rainfall. This can make the plant more vulnerable to water stress and hinder its ability to thrive in desert conditions.

Answer 3

because it would easily become dislodged, additionally desert plants normally have shallow, but extensive root systems in order to trap as much water as possible
