Creative Infographic Poster of the Cellular Photosynthesis Cycle

Educational infographic poster titled "Cellular Photosynthesis Cycle" in portrait layout, designed as a creative infographic poster for nature / biology, with sharp, readable sans-serif text labels and clearly enumerated numbered sections for expert reference. Compose 6 numbered components arranged in a clean vertical-to-circular flow with arrows and subtle dotted connector lines, each section featuring a bold English heading, a one-line English caption, and a precise scientific visual element.

1. heading: "1. Light Capture", caption: "Chlorophyll absorbs photons in the thylakoid membranes.", visual: detailed cutaway of a chloroplast showing stacked grana, highlighted thylakoid discs glowing with neon cyan light rays entering from the upper left, small pigment symbols embedded in the membrane.

2. heading: "2. Water Splitting", caption: "Water is split to release electrons, protons, and oxygen.", visual: close-up diagram of the thylakoid membrane with a labeled reaction-center icon, H2O droplets entering, oxygen bubbles exiting upward, tiny electron dots moving into a transport path, proton symbols accumulating inside the lumen.

3. heading: "3. Electron Transport", caption: "Excited electrons drive a membrane transport chain.", visual: stylized membrane-spanning protein complexes as retro science modules, glowing electron path shown by magenta arrow segments, proton pumping indicated by repeated small arrows across the membrane.

4. heading: "4. ATP and NADPH", caption: "Energy carriers are assembled from the light reactions.", visual: turbine-like ATP synthase cutaway spinning at the membrane edge, ATP icons emerging from one side, NADPH molecular badge forming beside a cofactor diagram, energy sparks in cyan and magenta.

5. heading: "5. Carbon Fixation", caption: "Carbon dioxide enters the Calvin cycle in the stroma.", visual: circular Calvin cycle diagram inside the chloroplast stroma, CO2 molecules entering from outside, enzyme-style nodes connected in a ring, one key molecule highlighted with a brighter neon outline.

6. heading: "6. Sugar Output", caption: "The cycle produces carbohydrates for cellular metabolism.", visual: hexagonal glucose icon emerging from the cycle, arrow leading toward a simplified plant cell energy-use panel, small starch granule symbols and branching metabolic arrows.

Show a master flow using sequence numbers, curved arrows from 1 to 6, and a return dotted loop from "Sugar Output" back toward the chloroplast context to imply the ongoing biological cycle. Include a slim side legend panel with compact mini-icons for "Light", "H2O", "CO2", "O2", "ATP", and "Glucose", all rendered with sharp readable English labels. Add subtle gridlines and measurement ticks to evoke an expert reference plate.

Visual style: retro 1950s science poster blended with futuristic biotech infographic aesthetics; magazine-grade editorial illustration, vector-clean lines, no photographic textures. Use a tech neon cyan & magenta palette with dark navy or charcoal background, cream-tinted retro paper accents, thin white annotation lines, geometric panel borders, and a precise educational mood that feels archival yet advanced. Keep the composition elegant, balanced, and highly legible, with no real-brand logos, no copyrighted characters, and no identifiable people.

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 watermarks Render labels and headings in clean English typography (sans-serif). No real-brand logos, no copyrighted characters, no people that could be identified, no graphic medical content. If the topic touches a regulated domain (medicine, finance, law), keep the explanation conceptual and add no specific dosages, prices or legal advice.
