Plant cell connections. Illustration of plants cells and the connections (plasmodesmata) that allow communication, signalling and transport between the cells. The cells are shown in sectioned view here, with each cell (rounded) having a cell nucleus (dark blue), a vacuole (light blue), and a primary cell wall (dark green). The plasmodesmata are the rods between the cells, with the cytoplasm (yellow) able to pass between cells. Between the cells is the area called the middle lamella (light green), a pectin layer that cements the cells together and provides rigidity. For this artwork without labels, see C023/8836.
