Embryonic Development Overview Scientific Infographic Diagram

Biological diagram infographic titled "Embryonic Development Overview" centered on a clean labeled developmental diagram in an evolutionary-tree layout, showing a biologically accurate branching progression from fertilized egg through early embryonic stages to major germ-layer-derived lineages, designed for university undergraduate education. Create a central editorial scientific illustration with vector-clean lines and medical-textbook clarity, no photographic textures. Use a modern textbook visual style, vibrant educational primary palette (blue, red, yellow, green accents), sharp readable typography, balanced white background, calm instructional mood. Arrange 5 labeled stages/components around the central tree with thin leader lines; each label must include a short heading in English and a one-line function description in English. Include subtle branching arrows to indicate developmental progression. Labels to render exactly as: "Zygote" — "Single fertilized cell that initiates embryonic development."; "Morula" — "Solid ball of blastomeres formed by early cleavage divisions."; "Blastocyst" — "Hollow stage with inner cell mass and trophoblast for implantation."; "Gastrula" — "Stage where germ layers form and the body plan is established."; "Germ Layers" — "Ectoderm, mesoderm, and endoderm give rise to specialized tissues." Show accurate relative morphology for each stage, with simplified but scientifically correct embryology forms, tasteful educational presentation, no gore, no blood, no patient imagery, no cruelty imagery. Include a small unobtrusive legend or caption style consistent with a modern biology textbook. 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.
