I liked the diagram of the leaf, it was really helpful and very accurate. However, you did make one mistake. Transpiration isn’t the whole process from roots to leaves, but only the process of evaporation and diffusion out the stomata. I learnt that oxygen leaves through the stomata because there is a high concentration in the leaf, while carbon dioxide enters because there is a high concentration outside the leaf.
