3d nucleus model

Create a 3D biological nucleus model matching a colorful educational science illustration. Semi-cutaway spherical nucleus with a smooth purple-pink nuclear envelope containing small pores, soft translucent pink nucleoplasm, a bright yellow glowing nucleolus at the center, subtle chromatin texture embedded throughout the interior, and folded golden-yellow endoplasmic reticulum wrapping around the lower exterior. Use glossy PBR materials, subsurface scattering, soft organic shapes, smooth membrane folds, vibrant colors, high-resolution textures, clean topology, realistic depth, scientific accuracy, studio lighting, isolated object on plain white background, educational medical illustration style, ultra-detailed, game-ready, Unreal Engine 5 quality. Negative prompt: text, labels, arrows, watermark, logo, BYJU'S, annotations, extra organelles, cell membrane, mitochondria, cluttered background, low poly, blurry textures, flat image, cartoon face, distorted anatomy.
