poikilohydric
Poikilohydric refers to organisms whose body water content fluctuates with that of their surrounding environment. Unlike homeohydric organisms, which maintain a relatively constant internal water balance, poikilohydric organisms do not possess sophisticated mechanisms for regulating their hydration levels. Their water content is largely dependent on the availability of water in their habitat.
This characteristic is common among many plants, especially those in arid or intermittently moist environments, such
Fungi also exhibit poikilohydric tendencies, particularly many saprophytic and parasitic species. Their growth and reproductive processes
