Description
can you answer these questions about cells and tissues (rod and cone cells of eye)?
1) How are organelles distributed in this cell? (i.e. are there more peroxisomes, less mitochondria, etc.) Why do you see this? Remember: “form follows function.”
2) In what type of tissue(s) and organ(s) would you find you find this cell? What is its role there?
3) Each type of cell in the body only uses a small part of its genome to function. For instance, red blood cells produce a lot of hemoglobin and are therefore “expressing” the alpha-hemoglobin and beta-hemoglobin genes. Are there certain genes that are over-expressed (turned on) in this cell? How do these genes help the cell’s function?

Organelle Distribution
Cones and rods cells perform different functions which ultimately include
photoreception. Like any other cell, the cones and rods have a nucleus at the middle of the cell,
which primarily controls the activities of the entire cell. However, the two types of cells are
differentiated in their activities by the concentration of different organelle, determined by their
photosensitivity levels under different light concentration. The cones are primarily useful in
detecting light under high intensity, in which case it would require a relatively higher amount of
light to trigger responsiveness from the cones than woul...
