The world is now facing many severe problems due to increasing global demands for already limiting food and energy resources. Plant reproduction is crucial not only for producing offspring but also for improving crop quality and yield. Moreover, plant reproduction entails complex growth and developmental processes, which offer various opportunities for elucidating fundamental principles in biology.
Most flowers have both the male and female reproductive organs, but some bear either the male or the female sex organs. Such flowers are known as unisexual flowers e. Those flowers which have both sex organs are known as bisexual flowers e.

Plant reproduction is the process by which plants generate new individuals, or offspring. Reproduction is either sexual or asexual. Sexual reproduction is the formation of offspring by the fusion of gametes. Asexual reproduction is the formation of offspring without the fusion of gametes.
Plants are living organisms. That means they need to reproduce in order to pass on their genes to future generations. Plants can create offspring through either sexual or asexual reproduction.

Sexual Reproduction in Flowering Plants. The angiosperms are seed-bearing plants that produce flowers. The seeds, which contain the plant embryo, are produced in the flower.
Plant reproduction is the production of new offspring in plantswhich can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametesresulting in offspring genetically different from the parent or parents. Asexual reproduction produces new individuals without the fusion of gametes, genetically identical to the parent plants and each other, except when mutations occur.
Sexual Plant Reproduction. As we enter the 21st year of the journal Sexual Plant Reproductionit seems both fitting and appropriate to consider the genesis both of this journal and its parent organization, the International Association for Sexual Plant Reproduction Research IASPRR —particularly through its much longer history of plant sexual reproduction congresses, informal interactions and this area of scientific pursuit as it is transformed in the modern era. Petersburg in and since that time has represented scientists working on various aspects of plant sexual reproduction ranging from molecular to structural levels.
