Question: 1 / 400

Which of the following is NOT one of the seven life processes?

Growth

Sensitivity

Cognition

Cognition is not one of the seven life processes. The seven life processes that are fundamental to all living organisms include movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition. Cognition refers to mental processes such as thinking, learning, and understanding, which are typically attributed more to animals with advanced nervous systems rather than being an essential process for all life forms.

In contrast, growth refers to an increase in size or mass, sensitivity is the ability to respond to stimuli in the environment, and excretion is the process of removing waste products from the body, all of which are critical functions necessary for the survival of living organisms. Understanding these distinctions is crucial in recognizing the fundamental characteristics that define life.
