The formation of a new plant that is either an exact copy or recombination of the genetic makeup of its parents. There are three types of plant reproduction considered here: (1) vegetative reproduction, in which a vegetative organ forms a clone of the parent; (2) asexual reproduction, in which reproductive components undergo a nonsexual form of production of offspring without genetic rearrangement, also known as apomixis; and (3) sexual reproduction, in which meiosis (reduction division) leads to formation of male and female gametes that combine through syngamy (union of gametes) to produce offspring.
