Question

Which organelle is responsible for producing energy (ATP) in the cell?
<!-- AI image prompt | slot:animal_cell_v3 | paste into Gemini/DALL-E/Midjourney: STRICT RULES — OBEY EVERY ONE OR THE IMAGE IS UNUSABLE:
(1) The image contains EXACTLY these text labels and nothing else: "Nucleus", "Mitochondrion", "Endoplasmic reticulum", "Golgi apparatus", "Ribosome", "Lysosome", "Cell membrane". (2) The following words MUST NOT APPEAR anywhere on the image, in any form, abbreviation, casing, or plural: powerhouse, ATP, energy, produces, produces ATP, function, controls, synthesis, Site of, cellular respiration, central control. (3) ZERO arrows other than those explicitly described. ZERO icons or illustrations not explicitly described. ZERO highlighting/glow/circle around any structure. (4) ZERO title, heading, caption, watermark, signature, color legend, key, scale bar, page number. (5) Background: pure flat white (#FFFFFF). (6) ALL labels (when present) use identical typography (same font, size, weight) and identical leader-line style — no label is emphasized over another.

SUBJECT: Photorealistic textbook illustration of a single animal cell in cross-section. Canvas 1400x900, white background, soft natural shading. Cell occupies ~80%% of frame, centered. STRUCTURES: large central nucleus (dark purple, double envelope, visible nucleolus); 4 mitochondria scattered (bean-shaped, pink-orange, visible cristae); rough endoplasmic reticulum (winding light-blue membrane network with ribosome dots); Golgi apparatus (stack of 5 flat curved golden-yellow sacs); free ribosomes (tiny black dots in cytoplasm); 2-3 lysosomes (small round light-gray vesicles); thin clear cell membrane outer boundary. LABELS: thin black leader line from each name to its structure. Bold sans-serif ~22pt, identical for all seven labels. FINAL REMINDER: NO function descriptions in any form (no 'powerhouse', 'ATP', 'energy', 'controls cell', 'protein synthesis'). Names only. -->
