Photosynthesis Cycle Infographic for Biology Study

Biological diagram infographic titled "Photosynthesis Cycle". Center the composition around a clean labeled circular flow diagram of photosynthesis for a university undergraduate audience, showing a chloroplast-centered cycle ring with directional arrows connecting the major stages and exchanges. Arrange exactly 7 labeled stages/components evenly around the circular flow, each with a thin leader line, a short label in English, and a one-line function description in English. Depict a large central chloroplast cutaway with clearly defined thylakoid membranes, grana stacks, stroma, and membrane boundaries, while the outer circular layout shows the sequence and inputs/outputs of the photosynthesis process. Include subtle input → output markers for matter and energy flow. Labels to render exactly as: "Light Reactions" — "Convert light energy into ATP and NADPH at the thylakoid membrane."; "Photosystem II" — "Uses light to split water and release electrons, protons, and oxygen."; "Electron Transport Chain" — "Transfers energized electrons and helps generate a proton gradient."; "ATP Synthase" — "Produces ATP as protons flow across the thylakoid membrane."; "Photosystem I" — "Re-energizes electrons to drive NADPH formation."; "Calvin Cycle" — "Uses ATP and NADPH to fix carbon dioxide into sugars in the stroma."; "Glucose Output" — "Represents carbohydrate production for energy storage and biosynthesis." Add small supporting callouts integrated into the diagram for "CO2", "H2O", "O2", "ATP", and "NADPH" as flow markers only, without counting them as primary labels. Use biologically accurate chloroplast anatomy and pathway logic, with clear distinction between thylakoid lumen, thylakoid membrane, and stroma. Visual style: medical illustration (Netter-style), editorial scientific plate, monochrome scientific palette with refined grayscale and muted slate tones, soft ink shading, crisp contour lines, elegant textbook composition, calm academic mood. Ensure all text is sharp and readable, proportions are scientifically accurate, and the infographic emphasizes educational clarity over decoration. medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no graphic gore, no real patient photos, no watermarks No graphic medical gore, no real patient photographs, no surgical blood. For human anatomy, keep illustrations educationally tasteful. For animal anatomy, no cruelty imagery. Scientifically accurate labeling and proportions.
