The male reproductive organ is the Stamen and the female reproductive organ is the Stigma. Plants have both male and female reproductive organs because they can reproduce A-sexually however, most don't as this keeps the gene pool varied. The plant produces pollen male sex cell in the anther , which is the head of the stamen the other half is called the filament. This pollen will then be picked up by insects and spread to another plant.

Flower description glossary

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. Working in the IGC laboratories, the team used an extensive combination of genetic, pharmacologic and electrophysiological techniques to reveal the role of glutamate receptor-like GLRs genes and D-serine in pollen grains, and their physiological impact on plant reproduction. In proving that GLRs are calcium channels, the team also solved two long-standing riddles in plant biology: the molecular nature of calcium channels in the outer membrane of plant cells, a central question in plant physiology elusive for more than 20 years, and what are the functions of GLRs genes in plants, a fact that has puzzled biologists ever since the first genome of the model plant Arabidopsis was sequenced.

Male Reproductive Organs in Plants: Structure & Function

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.

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.
