Mechanisms of Plant Growth and Productivity: Investigating Biological Processes at the Molecular, Cellular, and Whole-Organism Levels

Arable land for agricultural production has been continuously decreasing over the past several years as a result of urban expansion. Although the output of agricultural produce has not been impacted in terms of quantity, innovations must be made to ensure that food production keeps up with the growing population. However, it is essential to first understand the mechanisms and interactions within plants that drive plant growth. This secondary research paper analyzes the biological processes that aid in plant growth and productivity, looking at the different mechanisms on a molecular, cellular, and whole-organism level. Specifically, photosynthesis, germination, and auxin-cytokinin signaling were the main processes discussed in this particular research paper. Through this analysis, it can be established that all three selected processes play an important role in plant development, with each contributing to the functionality of several key mechanisms in plants. Photosynthesis is the fundamental process through which the plant derives energy from light and sustains growth. Auxins and cytokinins regulate plant development, specifically in the roots and shoots, through an antagonistic relationship. Germination facilitates the transition of a plant from a seed to a sprout. A variety of peer-reviewed articles were utilized throughout the review process in order to synthesize a fully encompassing perspective, and bias was mitigated through the usage of articles from a variety of journals, years, and researchers. Certain limitations may reduce the effectiveness of this article, including the limited species of plants used in the examined sources. This research was conducted with the aim of connecting biological processes in order to understand their potential for plant development and crop yield. Therefore, this research could be used to aid in promoting the fulfillment of the United Nations Sustainable Development goals of no poverty, zero hunger, and good health and well-being.
