Therefore, damage to the right side of the posterior portion of the brain can cause a loss of the left field of view in both eyes. Likewise, damage to the left posterior part of the brain can cause a loss of the right field of vision. The most common causes of this damage include stroke, brain tumour and trauma. These are the visual fields of a patient with a right-sided hemianopia tested on a machine called a Humphrey Field Analyser.
The main difference between cytokinesis in animal cells and  cytokinesis in plant cells is how the division occurs. In animal  cells there is a formation of a cleavage furro â¦ w which gradually  squeezes the cell in half. In plants cells they form a cell plate  that gradually divides the cell in half.
Cytokinesis In Animal Cell: Animal cell has a plasma membrane. A cleavage is formed in the middle of the cell and then this furrow deepens until it meets the membrane. When the membrane fuses, the cell completely divides, forming two daughter cells. This cleavage formed is controlled by cytoskeleton elements which are responsible for pulling the plasma membrane inwards.
