Well for starters, they do not have leaves which reduces transpiration. They also grow really long roots that can absorb the smallest traces of moisture in the earth.

A. Multiple organ systems working together
Explanation:
All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.
