Question
Chapter 44.5, Problem 1CS
Summary Introduction
To explain: The structural similarity in insect and vertebrate photoreceptors.
Introduction: The eyes present in arthropods are known as compound eye, whereas eye present in vertebrates is known as a simple eye. The eyes in both of them help in better interaction with their surroundings and can also sense colors present in the environment.

Light sensitivitylabel the discussions with titlesDiscussion 1 – Answer in 100 – 150 WordsThere is a relationship between eye color and sensitivity to light. What is that relationship exactly and what causes some color eyes to be more sensitive than others? Discussion 2 – Answer in 100 – 150 WordsExplain the process of perception. Discussion 3 – Answer in 100 – 150 WordsDo humans actually have a “blind spot?” If so, what causes this blind spot and what are some disadvantages of it? Discussion 4 – Answer in 100 – 150 WordsThoughts? Discussion 5 – Answer in 100 – 150 WordsRefer to Figure 3.25 (b) in Ch. 3 of Sensation and Perception. Typically, the right side of the body is controlled and interpreted by the left hemisphere of the brain, and vice versa. How is this different in the visual system? Why? Discussion 6 – Answer in 100 – 150 WordsDescribe the role of light receptors…
Include a 5-10 sentence explanation of how the sheep’s eye senses light and relays that data to the brain to interpret visual information. Some pieces to consider:
What path does the light travel?
What structures and pigments does it interact with?
How does the signal travel to the brain?
Where in the brain is the data processed?
How is this different in the high light vs low light?
How might the sheep’s vision differ from our own?
