Question 1. Explain the functional limitations of sense organs.
Answer: Sense organs function with certain limitations. For example our eyes cannot see things which are very dim or very bright. Similarly our ears cannot hear very faint or very loud sounds. The same is true for other organs also. As human beings, we function within a limited range of stimulation. For being noticed by a sensory receptor a stimulus has to be of an optimal intensity or magnitude.

Question 2. What is meant by light and dark adaptation? How do they take place?
Answer: Bright adaptation refers to the process of adjusting to bright light after exposure to dim light. This process takes nearly a minute or two. Dark adaptation refers to the process of adjusting to a dimly illuminated environment after exposure to bright light. This may take half an hour or even longer depending on the previous level of exposure of the eye to light. The dark-adapted eye is about 100,000 times more sensitive to light than the light-adapted eye.
