Kling 2.5 Turbo (pro)
"Use my uploaded cell image as the base frame. Keep the cell's original shape, color, and microscopic details unchanged. Create a subtle, realistic animation showing gentle intracellular activity. The cytoplasm should exhibit slow natural streaming, tiny organelles should move slightly in random directions, and the cell membrane should have a soft, almost imperceptible pulsating motion. Add delicate floating particles inside the cell to simulate active metabolism. Keep the movement smooth, scientific, and minimal—no exaggerated motion, distortion, or camera shake. Maintain the original image quality and realism with a clean microscopic laboratory appearance. Cinematic lighting, ultra-realistic biological animation, 4K quality, seamless 5–8 second loop."
