How many stages are in each plant life cycle?

It really does depend on the organism in question, for example some species like dragonflies include metamorphosis, which completely transforms their appearance- some species include larval stages, like butterflies. Some species on average live only for a day or two, like some species of Mayfly! But all have a life and death stage, some have a 'teenage' stage, some a child/young stage and so on. It really does depend on the animal- imagine a human before it becomes an adult curling up into a ball and constructing a cocoon around its body and hangs on a leaf (or tree, mind the weight)!
