Component Parts Of The Eye Gcse Biology Revision Science Revision Biology The eye is a sense organ containing receptor cells which are sensitive to light intensity and colour. the purpose of the eye is to receive light and focus it onto the retina at the back of the eye. there are two main functions of the eye: accommodation to focus on near or distant objects. adaptation to dim light. The iris is a muscle which controls the size of the pupil by contracting or relaxing. this allows the eye to adjust to bright and dim lighting. describe the structure and function of the ciliary muscles and suspensory ligaments. the ciliary muscles and suspensory ligaments hold the lens in place and control its shape.
The Eye An Introduction Gcse Biology Study Mind Gcse; aqa; coordination and control the nervous system aqa the eye. the nervous system enables humans to react to their surroundings and to coordinate their behaviour. The eyes example questions. question 1: describe how light enters the eye. [4 marks] gcse biology foundation biology higher aqa. show answer. question 2: explain how the eye responds to dim light. [3 marks] gcse biology foundation biology higher aqa. show answer. The eye is a sense organ containing receptors sensitive to light intensity and colour. receptors are groups of specialised cells that can generate an electrical impulse in a sensory neurone. the eye contains two types of receptor cell: rod cells which are sensitive to light intensity and cone cells which are sensitive to different wavelengths. The eye is a sense organ containing receptors close receptors organs which recognise and respond to stimuli. sensitive to light intensity and colour. figure caption, the structure of the human eye.

The eye is a sensory organ, and therefore it follows similar principles to what we learnt about earlier – i.e. it has receptors to detect a stimulus, and then transmits information via an electrical impulse to a coordinator, the brain, before initiating a response via effectors. the eye is also involved in reflexes, which we learn about below.
