Quizplus · Accepted Answer

A psychrotroph is an organism that can grow slowly in the cold (around 0-20°C) but has an optimum growth temperature of around 20-30°C. This is different from psychrophiles (option C), which can grow well in the cold but have a much lower optimum growth temperature, and thermophiles (option B), which have a much higher optimum growth temperature. Extremophiles (option A) are organisms that can survive in extreme conditions like high or low temperature, pressure, or pH. Lastly, thermoduric (option E) refers to organisms that can survive high temperatures but cannot necessarily grow at those temperatures.
