Photosynthesis Process Explained: Light Reactions & Calvin Cycle #2173333 (License: Personal Use)

This diagram depicts the two main stages of photosynthesis occurring within a plant chloroplast: the light-dependent reactions in the thylakoid membranes (producing O₂, ATP, and NADPH) and the light-independent Calvin cycle in the stroma (fixing CO₂ into glucose). Arrows indicate inputs (sunlight, H₂O, CO₂) and outputs (O₂, sugar), with key molecules like NADP⁺/NADPH and ADP/Pi shown cycling between stages. The structure highlights the spatial organization essential for efficient energy conversion.

Used in biology education, textbook illustrations, or science websites explaining plant physiology; targets students, teachers, or curious learners seeking a visual breakdown of photosynthesis mechanics.
