Science — AI-generated practice question

Amoeba is a unicellular organism that follows holozoic nutrition. It captures food using temporary finger-like extensions called pseudopodia, which engulf the food particle by fusing around it, forming a food-vacuole. Inside the food-vacuole, complex food substances are broken down into simpler ones by enzymes. These simpler substances then diffuse into the cytoplasm for use. The remaining undigested material is moved to the cell surface and thrown out (egested).

• Examiners look for four key steps: ingestion (pseudopodia), digestion (food-vacuole), absorption (diffusion into cytoplasm), and egestion.
• Mention pseudopodia and food-vacuole by name — these are the technical terms that earn marks.
• "Holozoic nutrition" is a good addition but not strictly required; the process description is what's marked.
• Do not confuse Amoeba with Paramoecium (which uses cilia at a fixed spot).
