They occur in the aerial roots of Monstera and in the roots of Nymphaea. The stems and petioles of [...]
In this article we will discuss about the mechanical tissue in plants. This will also help you to draw the structure and diagram of mechanical tissues in plants. The tissue that supports a plant and their growing organs against any deformation and provides mechanical strength is termed as mechanical tissue. Haberlandt (1914) called the mechanical tissue as stereome. Schwendener in [...]
