Sexual reproduction is the production of a new organism from two parents by making use of their gametes or sex cells. Plants also have male and female sex organs. These sex organs in plants are carried within the flower and the seeds which are inside a fruit. Such plants are called angiosperms or flowering plants as they reproduce by sexual reproduction method. Most of the plants contain reproductive organs of both male and female in the flowers. The same flower has both male and female reproductive organs.

Plant reproductive morphology is the study of the physical form and structure the morphology of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers , which are the reproductive structures of angiosperms , are the most varied physically and show a correspondingly great diversity in methods of reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel studied the reproduction of flowering plants and for the first time it was understood that the pollination process involved both biotic and abiotic interactions. Charles Darwin 's theories of natural selection utilized this work to build his theory of evolution , which includes analysis of the coevolution of flowers and their insect pollinators. Plants have complex lifecycles involving alternation of generations. One generation, the sporophyte , gives rise to the next generation asexually via spores.
Plant reproductive morphology
Plant reproductive system , any of the systems, sexual or asexual, by which plants reproduce. In plants , as in animals , the end result of reproduction is the continuation of a given species , and the ability to reproduce is, therefore, rather conservative , or given to only moderate change, during evolution. Changes have occurred, however, and the pattern is demonstrable through a survey of plant groups. Reproduction in plants is either asexual or sexual.
This study not only reveals a new mechanism which underlies reproduction in plants, but also opens an exciting new avenue in the study of how cell-cell communication is conserved between animals and plants. For many years biologist have observed regular oscillations in several parameters that control growth of pollen tubes, such as pH concentration of proton ions and calcium ions, but the actual molecular channels that control these oscillations and their physiological output have remained elusive. Both D-Ser and GLRs are key molecular players in cell-cell communication in the animal central nervous systems, at various levels: they play a central role in memory and learning processes in the brain, and have been implicated in a wide range of neurodegenerative diseases such as multiple sclerosis, Alzheimer, Huntington's disease and others. And now, surprisingly, they also have a role in reproduction of plants.
