Botanies metabolize themselves through photosynthesis, and leaves are the main organs for this process. With the help of phytochrome such as chlorophyll and of visible light. green plants can convert carbon dioxide and water to organic material and release some amount of oxygen.The molecular equation is shown below:
CO2+H2O→(CH2O)(ORGANIC MATERIAL)+O2(CONDITIONS: LIGHT ENERGY AND CHLOROPLAST)
Leaf mosaic is caused by the difference of the length,distortion,and arranging angle of the leaves. which causes a disclosed pattern of the leaves but not coicided pattern. Viewed from the top, the phenomenon of leaf mosaic is even more obvious,especially for those plants that have short time interval and many foliage on the stem such as tobacco, dandelion,and snokeweed.
