Well, there can either be one answers out of the two answers:
1. They wanted to get eaten by the cops so they disguised them as jelly doughnuts.

2. When a red blood cell matures it pushes out its nucleus. Its internal structures go through a shape change, giving the cell a "doughnut" shape but just flat in the middle, without a hole. This shape allows for more surface area to bind oxygen and carbon dioxide during gas exchange. The bi-concave disc shape also makes the cell more flexible so that it can get through the smaller blood vessels.
I would go with 2. ;)
It is a donut shape.
There are two forms of the red blood cell: Donut-shape (the normal shape) and Sickle cell. By having Sickle cells, you are immune to Malaria, but you have a higher risk of blood clots.
well simply by identifying it's signature "donut" shape, also, it is red
It gives the cell structure and shape
It is the cell wall which gives the cell a definite shape
The cell wall protects and gives shape to a plant cell.
It depends on d type of cell;white blood cell and blood platelets are amoeboid in shape;red blood cell is round and biconcave in shape
Gives the cell nutrients and gives it shape
The red blood cells that transport oxygen in the blood are circular in shape with the center compressed - kind of like a donut, but where the hole would be is a "well" of tissue. It is shaped like this because this shape increases the surface area of the cell and allows it to carry more oxygen. The shape makes it more efficient.
