In this article we will discuss about the process of thickening of cell wall in plants, explained with the help of suitable diagrams. The cell plate separates the two protoplast of a dividing cell. The cell plate gives rise to the middle lamella upon which the wall materials are laid down to form primary wall. During cell growth, each daughter [...]
In this article we will discuss about the structure of a cell wall in plants. This will also help you to draw the structure and diagram of cell wall in plants. Gross Structure of Cell Wall: A plant cell may consist of either primary wall only or the cell may contain both primary and secondary walls (Fig. 3.1). i. Primary [...]
Growth of cell wall involves the growth in surface area as well as growth in thickness. Normally, the entire cell wall grows. Localized growth occurs in fibres, root hairs, tracheids and pollen tubes. A new primary wall grows in surface area. The wall expands due to the turgor pressure exerted on the walls by the protoplast. Turgor pressure is developed [...]
