Photosynthesis Pathway Infographic | Vintage Scientific Plate

Biological diagram infographic titled "Photosynthesis Pathway". Center the composition around a clean labeled diagram showing the photosynthesis pathway in a chloroplast and leaf context, arranged as a clear input → output flow for university undergraduate learning. Main central artwork: an editorial-grade botanical cutaway of a green leaf linked to a detailed chloroplast cross-section, with the pathway flowing left to right from energy and raw material inputs to sugar and oxygen outputs. Include subtle directional arrows connecting stages and materials, with 7 labeled components arranged neatly around the central diagram, each connected by a thin leader line, each with a short label in English and a one-line function description in English. Use biologically accurate naming and proportions.

Include these 7 exact labels and captions on-image:
1. "Sunlight" — "Provides photon energy that drives the light reactions."
2. "Leaf" — "Main photosynthetic organ that captures light and exchanges gases."
3. "Chloroplast" — "Organelle where light reactions and carbon fixation occur."
4. "Thylakoid Membranes" — "Contain chlorophyll and produce ATP and NADPH from light energy."
5. "Stroma" — "Fluid matrix where the Calvin cycle fixes carbon dioxide into sugars."
6. "Carbon Dioxide In" — "CO2 enters the leaf and supplies carbon for glucose synthesis."
7. "Glucose and Oxygen Out" — "Photosynthesis produces sugar for storage and oxygen for release."

Show pathway markers for inputs and outputs: input arrows for light and carbon dioxide entering the system, internal arrows from thylakoid light reactions to stroma carbon fixation, and output arrows for glucose and oxygen leaving the system. Add a small secondary indication of water entering the chloroplast near the light reactions without making it a primary label. Emphasize the relationship between leaf tissue, chloroplast structure, thylakoids, and the Calvin cycle with textbook-level clarity.

Visual style: vintage 1900s scientific plate, natural anatomy tones palette, muted greens, sepia ink, parchment cream background, restrained botanical shading, elegant engraved linework, classic academic composition, scholarly and calm mood. All text sharp and readable. medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. No graphic medical gore, no real patient photos, no surgical blood, no cruelty imagery.

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.
