Rods.
Cones and Rods are the two photoreceptors in the retinas. Cones sense 3 main types of colors (red, green, blue) which would be in daylight. Rods are more numerous, which are more light sensitive in order to see in darkness.
No, those are mostly the functions of the rod cells. Cones are more for vision during the day, when you can see colours :)
What other organ do you have to see with? Of course you use your eyes to see body cells (and everything else too). You will have to use a microscope too, to make the cells look large enough for you to see them though.
how do cells of the onion specimen appear under the microscope
I think when you rub your eyes you create pressure in your eyes so the only way for your brain to process light would be to make light. this is called pressure phosphenus.
Animals that hunt at light are much more ensitive to light than you or I. Even when we see only black, there is still enough light to them to see clearly. These would include cats and owls and skunks and opposums, etc.
The special layers of cells that are located in the back of a cats eyes improve the cats night vision. Cats are able to see far better than humans at night.

Not with the naked eye, but with a microscope.
Bats have eyes and can see both at night and during the day using their eyes. However bats do not rely on their eyes at night (in the dark), because they have another sense they use called "echo location" which works better than their eyes.
Cats eyes expand at night because They are bringing in more light to see into their eyes
so that they can see at night
Because to see at night
So they can see better at night.
We would be able to see with night-vision during the night.
because its eyes are for uses at night.
no they do not have yellow eyes but they do have a greyee ting
There are some cells below our eye balls . These cells send information to the brain what we are seeing . Just after a fraction of second we can see through our eyes .
