Which light sensitive cells (rods or cones) are able to provide better resolution and color information, but only work well during periods of sufficient lighting? What makes them able to do this? (1 pt) 5. How would your vision be affected if you had cataracts (clouding of your lens)? (1 pt) 6. Knowing what the pituitary gland does, what might happen if you had a tumor that was disrupting the gland's function? (1 pt)Explanation / Answer

3. Blind spot is actually a optic nevre head present in retina. And because of no photo receptors cells are present at that area no image formation hence that part of retina is blind and knows as blind spot.
4a. RODS are better in low light conditions and they make difference in shapes and size of objects and transmit signal in grey scale. Very less amount of photon energy activates them and makes them able to form an image.
4b. Cones are responsible for production of color and better resolution. They gets active when large amount of light is available. Then cone cell forms an images by making differences in the wave length of the light of the object that is reflecting and entering into eye.
5. Cataract affect the vision by clouding of lens of eye. Due to cataract an individual can experience blurry vision, faded color, trouble seeing in night etc.
6. If any tumor disrupting the pituitary gland function an individual can experience vision changes, headache, hormonal imbalance, interference with menstruation cycle and sexual dysfunction.
