The cells that make up the hydathode are called epithems. Aqueducts are made up of a bunch of living cells. Cells are watery and have intercellular spaces. The cells do not have chloroplasts. Each hydathode has one or more pores. Its pore is structurally similar to a leaf pore. But somewhat large in size and unable to move. It consists of one or more chambers. The chambers open into windpipe or trachea.
