Multicellular organisms grow and develop by reproducing, responding to the environment, maintain an internal stable environment, use materials and energy and consists of cells. Reproducing is really important. Reproducing helps multicellular organisms to develop and grow faster. Without it, no organism can survive. Responding to the environment is also important. This is where hibernation occur, along with homeostasis. Materials are also important.
DNA shapes how an organism grows up and the physiology of its blood, bone, and brains. DNA is thus especially important in the study of evolution. The amount of difference in DNA is a test of the difference between one species and another â and thus how closely or distantly related they are.he percentage of genes or DNA that organisms share records their similarities. We share more genes with organisms that are more closely related to us. Humans belong to the biological group known as Primates, and are classified with the great apes, one of the major groups of the primate evolutionary tree.
