This plays an important role in how a plant can heal itself after a wound. This process is responsible for healing in plants, from giant trees to a blade of grass. This is the American water weed's most important method of spreading, while seed production plays a relatively minor role. What is the function of the nucleus? Humans, plants and mushrooms are all alive. Simply through sheer numbers, parenchyma cells outnumber the other types. It can be used for science experiments in classrooms demonstrating how plants use carbon dioxide with the usage of bromothymol blue. F Stage : Platform where a slide is placed.
