I have chosen the eukaryotic cell, the cone cell located in the retina of the eye because the eye is very complicated and interests me because my eyes are not perfect, also my father is affected by colour blindness which is a problem directly linked to the cone cell in the retina. In the average human eye there are around six to seven million cone cells in total. The cone cell is made up of two parts, the outer segment and the inner segment. The outer segment holds the membranous discs which pigment the colour which is perceived by the cone cells. The membranous discs also contain transmembrane proteins which help transmit signals through the membranous discs. The outer segment is also responsible for absorbing the colour. The inner segment holds the organelles essential to …show more content…

The organelles found in cone cells are the nucleus and the mitochondria. The nucleus is the cell’s control centre and contains the genetic information that allows the cell to reproduce. Other organelles in the cone cell are the mitochondria. The mitochondria use the process of cellular respiration to take biochemical energy from nutrients and distribute it throughout the cell and therefore controlling the cell’s growth. The nucleus is located in the middle of the inner segment and the mitochondria are located at the top of the inner segment. Connecting the two segments is the cilium. At the base of the cell is the synaptic terminal which takes the colour perception from the cone cell and transmits it to the brain.

System. The Visual System is composed of 3 major parts. These are the eye, all parts responsible for transporting the signal including the optic nerve and the
