Infographie template biologie en coupe arc-en-ciel

Educational infographic poster titled "Biology Infographic Template" in portrait layout, designed as a reusable nature/biology infographic template with sharp, readable sans-serif text labels and clearly numbered sections. Create a detailed cutaway technical diagram aesthetic for enthusiasts, using a vibrant rainbow palette with structured editorial composition. Show 9 numbered components arranged in a clean vertical sequence with connecting arrows and subtle dotted guide lines, each number in a colored circle, each section containing a bold heading, a one-line caption, and a precise visual element.

1. heading: "Title Block", caption: "Main topic banner for a biology diagram template.", visual: large top header panel with leaf and cell icons, thin rule lines, small subtitle area, and a decorative rainbow gradient strip.
2. heading: "Habitat Overview", caption: "A cutaway landscape introduces the ecosystem context.", visual: cross-section of soil, grass, roots, rocks, water layer, and small inset labels pointing to terrain zones.
3. heading: "Cell Structure", caption: "Microscopic anatomy panel for labeling organelles.", visual: large biological cell cutaway with nucleus, membrane, mitochondria, vacuole, chloroplast-like organelles, and fine leader lines to blank-style label anchors.
4. heading: "Plant Anatomy", caption: "Exploded botanical diagram highlights functional parts.", visual: technical cutaway of a flowering plant with roots, stem, leaves, veins, bud, and internal water transport tubes shown in section.
5. heading: "Life Cycle", caption: "Circular sequence maps key developmental stages.", visual: ring diagram with seed, sprout, juvenile plant, mature plant, flower, fruit, and seed return, linked by curved arrows.
6. heading: "Energy Flow", caption: "Arrows trace sunlight, nutrients, and biomass transfer.", visual: sun icon feeding a plant, then herbivore silhouette icon, then decomposer fungi and soil nutrients, using color-coded directional arrows.
7. heading: "Internal Systems", caption: "Cutaway detail reveals transport and exchange pathways.", visual: magnified stem and leaf cross-sections showing xylem-like tubes, phloem-like channels, stomata pores, and gas exchange arrows.
8. heading: "Data Panel", caption: "Charts and metrics area for comparative biology facts.", visual: compact sidebar with bar chart, radial chart, specimen scale ruler, legend box, and metric callout placeholders rendered as technical infographic elements.
9. heading: "Key & Notes", caption: "Legend explains colors, symbols, and diagram logic.", visual: bottom panel with icon legend for water, light, nutrients, growth, reproduction, and observation markers, plus note lines and micro-diagram symbols.

Connect all sections with a clear instructional flow: downward arrows from 1 to 9, side dotted connectors to inset diagrams, circular arrows in the life-cycle panel, and fine technical leader lines from labels to structures. Emphasize modular template logic while keeping the biology visuals specific and informative.

Visual style: cutaway technical diagram, magazine-grade editorial illustration, vector-clean lines, no photographic textures. Use a vibrant rainbow palette distributed intelligently across numbered sections: red, orange, yellow, green, cyan, blue, indigo, violet, and magenta accents, balanced with white background, dark charcoal outlines, and subtle pastel fills for clarity. Mood: precise, energetic, scientific, polished, highly organized, modern educational reference poster.

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.
