This document compares the cell structure, nutrition, and number of cells in five kingdoms - Animals, Plants, Fungi, Protoctista, and Prokaryotes. It notes that animals are multicellular with nuclei but no cell walls or chloroplasts, obtaining nutrition from organic substances made by other organisms. Plants are also multicellular but have nuclei, cell walls made of cellulose, and often chloroplasts, obtaining nutrition via photosynthesis. Fungi are usually multicellular with nuclei and cell walls not made of cellulose, lacking chloroplasts and obtaining nutrition through saprophytic or parasitic means.
