What is the opening in the middle of the iris that controls the amount of light entering the eye is called?
PUPIL. It automatically becomes smaller due to contraction of Circular muscles via action of Parasympathetic nerve fibers, if light is more. And becomes bigger in size, if light is less due to contraction of the Radial muscles, via Sympathetic nerve fibers. This happens in order to protect Retina from excessive light. When there is total Solar eclipse and you go on looking at Sun, pupil will not contract and Retina gets excessive radiation from the surrounding of Sun and there by burning Retina, with permanent damage to it, causing total blindness.

What controls the amount of light that gets to the slide on the stage of a microscope?
The diaphragm located under the stage of a microscope controls the amount of light that reaches the slide. Adjusting the diaphragm controls the size of the opening and therefore the intensity of the light passing through the slide.

It has different sized holes and is used to vary the intensity and size of the cone of light that is projected into the slide

Why does the pupil get smaller when a bright light is shone in the eye?
Our pupils adjust to absorb enough light to see, but not so much that it damages our eyes. So when a bright light is shined in the eye, the pupil closes so that the eye isn't damaged. That's why doctors make you wear sunglasses after they dilate your eyes.

How does the iris control how much light enters the eye?
The iris is the coloured membrane in the eye that controls the amount of light entering the eye by expanding and contracting. The pupil is a hole in the centre of the iris. By expanding, more light will enter the pupil and by contracting less light will enter the pupil.http://en.wikipedia.org/wiki/Iris_(anatomy)
