Cones

1. Cones By: Caleb Earley

2. Where Cones are found • The cone cells are located in the human eye • More specifically found in the retina of the human eye

3. The Human Eye • The human eye contains many parts, 1 called the retina • The retina is made up of 2 different photoreceptors • 1 being the more sensitive to light then the other and contains about 120 million cells in the eye, these are called Rods • The other 1, Cones have much fewer cells only about 6-7 million in the retina and are less sensitive to light but much more sensitive to colour

4. Function of cones • Cones are cells in your eyes that give you the ability to see coloured objects • Cones turns light into colour • There are 3 different types of cones, green cones, red cones, and blue cone • The red and green cones make up about 98% of all cones • The blue only take up about 2% but, they have the highest sensitive color

5. Difference in rods and cones • Rods are very sensitive to light and are used during the night when it is hard to see • Cones however are only Useful during the day when it’s light. • Cone are also much smaller in size and have a substantial amount less In the retina

6. Condition that associated with cones • Colour blindness • For the most part Colourblindness is a hereditary condition • It occurs when 1 or more of the three types of cone cells are lacking or are not there
