儿童科学绘本细胞剖面图

一幅儿童科学绘本插图，扁平化截面图风格，展示单个动物细胞放大内部结构。细胞膜为半透明青绿色厚圆边框，细胞核居中为紫色球体，核仁更深。线粒体为粉色橄榄球形散布四周。内质网呈波浪形淡紫色丝带，核糖体为金色小点附着其上。每个结构以无衬线标注线引出粗体文字：「Nucleus」、「Mitochondria」、「Cell Membrane」、「Endoplasmic Reticulum」、「Ribosome」。配色明亮友好，适合儿童阅读。

A children's science book illustration using a clean flat-design cutaway diagram style, revealing the interior of a single animal cell magnified enormously. The cell membrane is shown as a thick rounded outline in translucent teal. Inside, the nucleus sits centrally as a round purple sphere with a visible darker nucleolus dot. Mitochondria are scattered as pink football-shaped organelles. The endoplasmic reticulum is illustrated as a wavy ribbon in pale lavender. Ribosomes appear as tiny gold dots along the ribbon. Each structure has a clean sans-serif label line leading to a bold label: "Nucleus", "Mitochondria", "Cell Membrane", "Endoplasmic Reticulum", "Ribosome". Color palette is bright, friendly: teal, purple, coral pink, lavender, gold on white. No photography. Style is approachable and non-intimidating — rounded forms, no harsh shadows, slight drop-shadows only under labels. Composition is centered with equal white margin on all sides.
