From the location in the (cross section of a) root where a lateral root starts to grow, what tissues will the lateral root have to grow through (in a dictor) to reach the outside edge of the root? Therefore, ensuring that the plant can survive for longer. As they are lateral extensions of a single cell and only rarely branched, they are visible to the naked eye and light microscope. Show it diagramatically. 0 0. Are trees multicellular or unicellular? The cell wall is of cellulose nature and forms permeable membrane and the plasma membrane around the vacuole forms the semi-permeable membrane.
