动物细胞白板动画

Hand-drawn diagram of an animal cell cut open to show its inside: one large rounded, slightly irregular blob-shaped cell with a thin soft pink outer cell membrane and no cell wall. Inside, the pale cytoplasm holds: one large round purple nucleus near the middle with a darker nucleolus dot inside it, three bean-shaped orange mitochondria with folded wavy lines inside, a stack of curved flat blue sacs (Golgi apparatus), wavy folded ribbons of rough endoplasmic reticulum dotted with tiny ribosome dots wrapped beside the nucleus, and two small round vacuoles. No chloroplasts, no cell wall, no large central vacuole. Nothing else in the picture. Coloured pencil and watercolour marker, clean black ink outlines, warm off-white paper, no text.
