Important Points to Remember about Reproduction in Lower and Higher Plants  : 

1. Reproduction is the process of production of new similar organisms from their parents.
2. In plants there are two modes of reproduction, asexual and sexual. There are several methods of asexual reproduction such as fragmentation, spore formation and vegetative propagation like  cutting, grafting, budding, layering, division, sectioning of rhizomes, roots, tubers, bulbs, stolons, tillers, etc.
3. Sexual reproduction involves the fusion of male and female gametes.
4. Asexual reproduction does not involve the production and fusion of male and female gametes.
5. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from the parent or parents.
6. The fusion of male and female gametes (fertilization) produces a diploid zygote, which develops by mitotic cell divisions into a multicellular sporophyte.
