Human Embryonic Development Infographic | Cell Structure and Its Parts

Biological diagram infographic titled "Human Embryonic Development" centered on a clean labeled circular life-cycle diagram showing early human embryonic development stages in clockwise sequence with directional arrows, simple and educational for kids ages 8–12, scientifically accurate proportions, tasteful medical illustration. Show 7 labeled stages arranged evenly around the central cycle ring, each stage with a thin leader line, a short English label in quotes, and a one-line English function caption in quotes: 1. "Fertilization" — "Sperm joins egg to form one new cell." 2. "Zygote" — "The first single cell contains all genetic instructions." 3. "Cleavage" — "The cell divides quickly into many smaller cells." 4. "Morula" — "A solid ball of cells forms after several divisions." 5. "Blastocyst" — "A hollow cell ball prepares to attach to the uterus." 6. "Implantation" — "The blastocyst attaches to the uterine lining for support." 7. "Embryo" — "Major body structures begin to form and grow." Include a small central overview image of the developmental sequence with subtle circular arrows, plus a tiny legend for timeline progression using simple markers "Day 0", "Day 3", "Day 5", "Week 2", "Week 4". Visual style: editorial scientific illustration, Netter-style medical illustration adapted for children, monochrome scientific palette with charcoal, slate gray, soft graphite, and pale gray highlights, calm classroom mood, high contrast sharp readable typography, clean white background, balanced spacing, vector-clean lines, gentle shading only, no photographic textures. Emphasize 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.
