Developmental biology is the branch of biology that studies the processes by which organisms grow and develop from a single cell into a complex multicellular organism. Developmental biologists investigate how genes and environmental factors interact to shape the structure, function, and behavior of organisms.
Differentiation and morphogenesis are closely related processes that are essential for the proper development of an organism. Differentiation produces the specialized cell types that are required for tissue and organ function, while morphogenesis organizes these cells into the complex structures that make up an organism.
Plants have evolved to respond to a wide variety of external and internal signals that enable them to adapt to changes in their environment and to coordinate their growth and development.
