Sexual reproduction allows a plant to perpetuate its species, meaning to give birth to a new plant. It requires male and female reproductive organs. There is another form of reproduction: vegetative reproduction (asexual reproduction). This involves the detachment of a piece of the plant (a stem, leaf or root) to create a new individual.
Angiosperm reproductive organs
The reproductive organs can be possessed by a single plant (monoicous species) or by two different plants of the same species (dioicous species).

These stages, which together form a plant's lifecycle, are common to all plants.
