One on branch and one on shoot apex. Secondary growth refers to lateral or increase in girth. Growth - increase in mass by cell division and cell expansion. Development all the changes that progressively produce and organism"s body (growth, differentiation, etc. ) Depending on which genes are turned on, which proteins are/aren"t made -> different cell types.

Genes that tell cells what to do determine what the cells are going to be when they are fully developed and matured. Know basic characteristics of diff cell types for exam. Cuticles waxy layer outside of shoot (shoot dermal cells) aids to lessen water loss. Dicot vascular bundle arranged in ring (pizza) Monocot vascular bundle scattered in no pattern.
