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.
Gametes, on the other han â¦ d, are haploid (n), with a single set of chromosomes, ie. half as many as the somatic cell. Now, the haploid chromosome number (n) is characteristic of the species, and in humans this number happens to be 23.Therefore a human gamete has 23 chromosomes, and a human somatic cell 23 pairs, or 46 chromosomes.hat depends on the organism you're looking at. In humans, there are 46 chromosomes per normal somatic cell. 46 chromosomes = 22 homolog pairs + 2 sex chromosomes (XX in w â¦ omen or XY in men).
