Embryonic Development Infographic with Labeled Stages

Biological diagram infographic titled "Embryonic Development" centered on a clean labeled developmental tree diagram showing major stages of embryonic development branching in a clear evolutionary-tree style layout suitable for high school / general audiences. Use a central vertical developmental sequence with gentle branching cues to indicate progression, not phylogenetic species relationships. Render 5 labeled stages/components around the central diagram, each connected with a thin leader line, a short label in English, and a one-line function description in English. Labels to include exactly: "Zygote" — "Single fertilized cell that begins rapid division."; "Morula" — "Solid ball of cells formed by early cleavage."; "Blastula" — "Hollow cell stage that prepares for implantation or further patterning."; "Gastrula" — "Stage where germ layers form and body axes are established."; "Neurula" — "Early organ-forming stage in which the neural tube develops." Show each stage with biologically accurate proportions and simplified textbook morphology, with subtle arrows indicating developmental progression from earliest to later stage. Add a small unobtrusive legend indicating developmental sequence. Visual style: modern textbook, vibrant educational primary palette, bright blues, reds, yellows, and greens with soft neutral background, friendly academic mood, high contrast readable typography, balanced spacing, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. All text sharp and readable. No graphic gore, no real patient photos, no cruelty imagery, educationally tasteful scientific presentation. 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.
