This week, to complete our unit on Biological perspectives, and classification, Class 7C undertook the study of photosynthesis in more detail. We learned how the process of photosynthesis, where plants use their green pigment in the presence of sunlight to make their food, and create oxygen as a waste product in doing so. The waste product of oxygen is the gas we need to survive, and we, in turn, provide the carbon dioxide for green plants to use to begin the process of photosynthesis.
Lichen is an organism that is formed through a symbiotic relationship between a fungi (Fungi Kingdom) and an algae (Protist Kingdom). The algae uses the fungi to help maintain moisture and the fungi uses the algae for its green pigment (chlorophyll) so it can photosynthesise.
By painting the trees with the lichen smoothie, we can help this organism grow in many areas and in turn help to make our environment healthier.
