Answer:
A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs.
Development involves cell division, body axis formation, tissue and organ development, and cell differentiation (gaining a final cell type identity).
During development, cells use both intrinsic, or inherited, information and extrinsic signals from neighbors to "decide on" their behavior and identity.
Cells usually become more and more restricted in their developmental potential (the cell types they can produce) as development progresses.
