Abstract
Photosynthesis is a vital process that drives life on Earth by converting light energy into chemical energy stored in glucose. It is the foundation of the food chain, supporting not only plant growth but also all life forms that rely on plants for sustenance. This review article synthesizes research on the mechanisms of photosynthesis, its significance to plant physiology, and its broader ecological and environmental implications. It draws from studies focusing on the biochemical processes, the relationship between photosynthesis and climate regulation, and advances in agricultural practices aimed at optimizing photosynthetic efficiency. Findings show that photosynthesis is not only crucial for plant growth and energy production but also plays a significant role in carbon sequestration and oxygen production, directly influencing global climate patterns. Enhanced photosynthetic activity has been linked to increased plant productivity, which is vital for food security in a changing climate. Photosynthesis is fundamental to life on Earth, underpinning food webs and contributing to atmospheric regulation. Understanding and enhancing photosynthesis through research can help mitigate climate change and improve agricultural productivity, ensuring a sustainable future for humanity.
