Plant reproduction can be accomplished by sexual or asexual reproduction. Asexual reproduction takes two main forms: Vegetative Reproduction and Apomixis - wikipedia 
Plants have a complex lifecycle involving alternation of generations. One generation, the sporophyte, gives rise to the next generation via Spores. The alternate generation, the gametophyte, produces eggs and sperm.
There is also a rich and complex diversity in Plant Sexual Morphology.
Plants have two main types of asexual reproduction in which new plants are produced that are genetically identical clones of the parent individual - wikipedia
Unlike animals, plants are immobile, and cannot seek out sexual partners for reproduction. In the evolution of early plants, abiotic means, including water and wind, transported sperm for reproduction - wikipedia
Flowering plants are the dominant plant form on land and they reproduce by sexual and asexual means. Often their most distinguishing feature is their reproductive organs, commonly called flowers - wikipedia
In plants that use insects or other animals to move pollen from one flower to the next, plants have developed greatly modified flower parts to attract pollinators and to facilitate the movement of pollen from one flower to the insect and from the insect back to the next flower - wikipedia
