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.

Plant Sex 101

Perhaps the most frequently asked questions about cannabis home growing is how to identify male or female plants and how to tell the difference. Every grower has asked these questions at some point. Luckily, each gender has unique characteristics that set them apart and help growers identify them easily. First of all, a Marijuana plant may be either male or female dioecious or hermaphrodite monoecious. Dioecious means each individual plant has either male or female reproductive organs.

Plant sexuality deals with the wide variety of sexual reproduction systems found across the plant kingdom. That plants employ many different strategies to engage in sexual reproduction was used, from just a structural perspective, by Carolus Linnaeus and to propose a system of classification of flowering plants. Later this subject received attention from Christian Konrad Sprengel who described plant sexuality as the "revealed secret of nature" and, for the first time, understood the biotic and abiotic interactions of the pollination process. Flowers, the reproductive structures of angiosperms, are more varied than the equivalent structures of any other group of organisms, and flowering plants also have an unrivalled diversity of sexual systems. But sexuality and the significance of sexual reproductive strategies is no less important in all of the other plant groups.
