A cross-section of a plasma membrane which is a type of membrane used in the cell membrane. The membrane is made up of multiple layers of cells each with a different color and shape. The cells are arranged in a grid-like pattern with the top layer being green the middle layer being yellow and the bottom layer being white. There are six cells in the image each representing a different type of plasma membrane. The first cell on the left side of the image is labeled "D1" the second cell is labeled as "D2" the third cell is labelled as D3 the fourth cell is numbered as D4 the fifth cell is marked as D5 the sixth cell is color-coded as D6 the seventh cell is green and all the cells are labeled with numbers and letters. The numbers range from 0 to 9 indicating the number of cells in each cell. The letters on the cells range from 1 to 9. - The cells appear to be made of a light-colored material possibly plastic or metal and they are connected to each other by thin curved lines. The background of the diagram is a light beige color which contrasts with the green and white colors of the membrane.
