Abstract
Background: Plant reproduction ensures the survival and diversity of plant species. Plants use both sexual and asexual methods of reproduction, each offering distinct advantages. Sexual reproduction involves the combination of genetic material from two parent plants, leading to genetic diversity. Asexual reproduction, on the other hand, allows plants to reproduce without the fusion of gametes, producing genetically identical offspring. Methods: This study explored sexual and asexual reproduction methods across different plant species, analyzing their mechanisms through a review of literature and observational data from selected plant species. Data was collected from field and greenhouse experiments involving species like Arabidopsis thaliana for sexual reproduction and Bryophyllum for asexual reproduction. Pollination, fertilization, seed germination, and vegetative propagation were observed and analyzed using microscopic, genetic, and statistical tools. Results: Sexual reproduction was found to increase genetic variation, contributing to greater resilience in changing environments. Asexual reproduction provided faster population growth in stable conditions. Sexual reproduction was more common in flowering plants, while asexual reproduction was predominant in species with poor pollination opportunities or those in extreme environments. Conclusion: Sexual and asexual reproduction methods provide evolutionary advantages based on environmental factors and species-specific needs. The choice between the two strategies is influenced by the availability of resources, environmental conditions, and genetic diversity requirements. A combination of both methods is seen in some species, enabling adaptation and survival across diverse ecosystems.
Keywords: Plant reproduction, sexual reproduction, asexual reproduction, pollination, genetic diversity, vegetative propagation, species survival.
