The coordinated morphogenesis process by which a leaf is formed and grows to become a mature photosynthetic organ is referred to as leaf development. It begins with the formation of a primordium in the shoot meristem and culminates in the fully structured leaf, which is made up of trichomes, guard cells, epidermal and mesophyll layers, and vascular cells. The leaf's photosynthetic capacity is the foundation for the entire plant's growth. It is critical to get a mechanistic understanding of leaf growth and development, as well as the effect of genetic and environmental factors on the process, in order to optimise crops for increased productivity and resistance in future climate scenarios. The basic building blocks of the leaf are cells, and the regulatory units that integrate genetic and environmental information into the developmental programme are cells.
