Photosynthesis in moss primarily happens in the leaves.
Mosses, being non-vascular plants, have simple structures. Unlike plants with roots, stems, and leaves that have vascular systems to transport water and nutrients, mosses absorb water and minerals directly through their surfaces. Once absorbed, these resources move either through or between cells to reach the leaves. It's within the cells of these leaves that chlorophyll is present, enabling the process of photosynthesis to occur. This process converts light energy, water, and carbon dioxide into glucose (sugar) for energy and oxygen as a byproduct.
In summary, while other parts of the moss plant may contribute in minor ways, the bulk of photosynthetic activity is concentrated in the leaves, where sunlight can be efficiently captured and converted into chemical energy.
