An organism that grows slowly in the cold but has an optimum growth temperature of 32°C is called
A)an extremophile.
B)a thermophile.
C)a psychrophile.
D)a facultative psychrophile.
E)thermoduric.

Question

Quizplus · Accepted Answer

A facultative psychrophile is an organism that grows slowly in the cold (below 20°C) but has an optimum growth temperature of 20-30°C. Therefore, choice D is the best answer as it describes an organism that grows slowly in the cold (psychrophile) but also has the ability to grow at higher temperatures (facultative). Option A, extremophile, refers to organisms that can survive extreme conditions such as high radiation, pressure, or temperature. Option B, thermophile, describes organisms that grow in high temperatures above 45°C. Option C, psychrophile, describes organisms that grow in cold temperatures below 20°C. Option E, thermoduric, describes organisms that can survive exposure to high temperatures but do not necessarily grow at those temperatures.
