In summary, the cornea is the clear, transparent front covering which admits light and begins the refractive process. It also keeps foreign particles from entering the eye. The pupil is an adjustable opening that controls the intensity of light permitted to strike the lens.ight rays pass through a dense, transparent gel-like substance, called the vitreous that fills the globe of the eyeball and helps the eye hold its spherical shape. In a normal eye, the light rays come to a sharp focusing point on the retina. The retina functions much like the film in a camera.

Best Answer: A somatic cell is a simple body cell (not a Germ cell-aka gamate) so therefore in a normal human cell, you have 23 PAIRS of chromosomes in each cell-this is 46 chromosomes in total which are maintained through the process of mitosis in each cell cycle.
Somatic cells (body cells) are haploid cells. They have 23 pairs of chromosomes. Reproductive cells (gametes) have half the normal number i.e. 23. This is because two gametes (one male and one female) have to fuse hence, restoring the original number of 23 pairs.here are 46 total chromosomes in a normal human body cell. They pair up, creating 23 pairs of chromosomes. Mutations can occur during cell division, causing human cells to have a varied amount of chromosomes-more or less. There are many genetic diseases caused by chromosomal mutations.
