Embryonic Development Overview Scientific Infographic

Biological diagram infographic titled "Embryonic Development Overview" centered on a clean labeled developmental tree diagram showing the major branching sequence of human embryonic development from fertilization to fetal stage, composed like an evolutionary tree with a central vertical trunk and branching milestones, suitable for university undergraduate biology. Render as a modern textbook scientific infographic with vibrant educational primary palette (clean blues, reds, yellows, greens), balanced white background, crisp typography, high contrast, sharp readable labels, medical-textbook clarity, editorial scientific illustration, vector-clean lines, no photographic textures. Show 5 labeled developmental stages arranged around the central diagram with thin leader lines, each with a short English heading and a one-line English function caption. Use biologically accurate proportions and naming, tasteful educational embryo illustrations, no gore. Label 1: heading "Zygote" caption "Single diploid cell formed by fertilization that begins cleavage divisions." Label 2: heading "Morula" caption "Solid ball of blastomeres produced by early cleavage without overall growth." Label 3: heading "Blastocyst" caption "Hollow stage with inner cell mass and trophoblast that prepares for implantation." Label 4: heading "Gastrula" caption "Stage in which ectoderm, mesoderm, and endoderm are established." Label 5: heading "Embryo to Fetus" caption "Organ systems form during embryogenesis and then enlarge and mature in the fetal period." Visually depict the sequence along the tree: fertilization at the base, cleavage progression upward, blastocyst branching into implantation and germ layer formation, then neurulation and early organogenesis leading to fetus at the top; add subtle directional arrows indicating developmental progression. Include small scientific callouts for "cleavage", "implantation", "gastrulation", "neurulation", and "organogenesis" near the central structure, but keep the 5 main labels dominant. 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.
