Developmental Biology is the branch of biology that studies how living organisms grow and develop from a single cell (like a fertilized egg) into a fully formed, multicellular organism. It focuses on the processes of cell division, differentiation, growth, morphogenesis , and organ formation , helping us understand how complex body structures and functions emerge during an organism’s life cycle. ๐Ÿงซ Key Concepts in Developmental Biology 1. Fertilization Fertilization is the union of a sperm and an egg to form a zygote (the first cell of a new organism). It triggers a series of biochemical and cellular changes that activate the egg and initiate development. 2. Cleavage After fertilization, the zygote undergoes rapid mitotic divisions called cleavage , producing many smaller cells called blastomeres .
