Reproduction in plants meant to be generation of new individuals or offspring. Reproduction in plants is either sexual or asexual. Sexual reproduction is done through the fusion of gametes whereas asexual reproduction is done through without the fusion of gametes.
In detail, sexual reproduction in flowering plants is done by the production of male and female gametes, and the transfer of male gametes to the female ovules through a process called as pollination. After this process of pollination, fertilization occurs which results in the production of fruits.
In other hand, asexual reproduction does not involve any union of cells, or nuclei of the cell. Typically it can be said that asexual reproduction only requires and only allows for only one parent. Asexual reproduction is otherwise called as vegetative propagation.
