Today, our topic is plant tissues. Before discussing about the tissues, here let's recall some points which we discussed in the previous chapter. Cell its structure and functions in living organisms. Living organisms in this world comprise of cells, right? There are unicerelar as well as multicerelar organisms present in this world. In unicerelar organisms only one single cell is capable of performing several functions, such as respiration, digestion and clearing of the cell. In multicerelar organisms there is a division of labor, right? Means there are different types as well as groups of cells that perform different functions. For example, in animal muscle cells are responsible for causing movement and in humans now cells are responsible for carrying messages.
