No, a protostar is basically the BEGINNING of a star's life cycle.
Life Cycle of a Star
Stars begin their life cycles in a nebula.
main sequence
Betelgeuse is currently in the red supergiant phase of its life cycle. It is near the end of its life and is expected to undergo a supernova explosion in the relatively near future (in astronomical timescales).
The gymnosperm life cycle usually takes two years to complete. The cycle begins as male cones release their pollen grains.
gametophyte as well as sporophyte generation
Onions are biennials, meaning they typically complete their life cycle in two years.
Plants do not go through complete metamorphosis.
Coleus plants are typically grown as annuals, meaning they complete their life cycle in one growing season.
Incomplete metamorphosis have three stages in the life cycle. Complete metamorphosis have four stages in the life cycle.
Sporozoa typically lack motility in their mature stages. They rely on host cells for movement and reproduction, often using a complex life cycle involving both sexual and asexual stages to complete their life cycle.
If it was in the wild the life cycle is from seedling to seedling and that is typically a year...

Annual flowers complete their life cycle in one summer.
A complete life cycle starts with seeds or birth, (plant or animal) and ends with death and decay.
