1. PLANTS AND PHOTOSYNTHESIS

Plants represent a fundamental group of organisms that possess the remarkable ability to convert sunlight into chemical energy. Through the complex process of photosynthesis, plants utilize chlorophyll to capture solar energy, subsequently transforming it into glucose, which serves as a primary energy source. The biochemical pathway of photosynthesis can be broken down into two distinct phases: the light-dependent reactions and the light-independent reactions, commonly known as the Calvin cycle.

During the light-dependent reactions, chlorophyll absorbs specific wavelengths of light, primarily in the blue and red regions of the spectrum. This energy is then utilized to split water molecules, a process that releases oxygen as a byproduct, while simultaneously generating adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH). These two molecules play pivotal roles in the subsequent phase of photosynthesis, facilitating the conversion of carbon dioxide into glucose during the Calvin cycle. Through this intricate biochemical machinery, plants effectively produce and store energy in the form of glucose, establishing themselves as primary producers in terrestrial ecosystems.
