Photosynthesis Pathway Botanical Infographic Diagram

Biological diagram infographic titled "Photosynthesis Pathway" centered on a clean labeled pathway flow diagram of photosynthesis in a plant leaf and chloroplast, showing input → output markers and directional arrows from reactants to products. Main composition: an editorial-grade botanical cross-section of a leaf with a magnified chloroplast inset, clearly showing where light capture, water use, carbon dioxide fixation, sugar formation, and oxygen release occur. Arrange 7 labels evenly around the central diagram with thin leader lines; each label must include a short English heading and a one-line English function caption. Use biologically accurate naming and scientifically correct relationships.

Include these exact on-image labels and captions:
1. "Sunlight" — "Provides photon energy that powers the light-dependent reactions."
2. "Leaf" — "Primary photosynthetic organ that captures light and exchanges gases."
3. "Chloroplast" — "Organelle where photosynthesis converts light energy into chemical energy."
4. "Thylakoid Membranes" — "Site of light reactions that produce ATP, NADPH, and oxygen."
5. "Water (H2O)" — "Supplies electrons and protons; splitting water releases oxygen."
6. "Carbon Dioxide (CO2)" — "Carbon source fixed in the Calvin cycle to build sugars."
7. "Glucose + Oxygen" — "Main outputs: stored chemical fuel and released oxygen gas."

Show pathway logic with clear arrows: "Sunlight" and "Water (H2O)" entering the thylakoid/light reaction zone, "Carbon Dioxide (CO2)" entering the Calvin cycle/stroma region, and output arrows leading to "Glucose + Oxygen". Add subtle secondary internal labels in the diagram for "Stroma" and "Calvin Cycle" only if space allows, while keeping the 7 main callouts dominant and readable. Emphasize medical-textbook clarity for a professional audience, with sharp typography, balanced spacing, and precise proportions.

Visual style: vintage 1900s scientific plate, natural anatomy tones palette, muted greens, warm beige paper tones, soft olive, sepia ink, restrained cream background, elegant engraved-science aesthetics. Overall mood: scholarly, archival, precise, refined. Render as medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. All text sharp and readable.

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.
