Consider statements about microorganisms: 1. Bacteria reproduce by binary fission. 2. Viruses have their own metabolic machinery. 3. Fungi have a cell wall made of chitin. Which are correct? MCQ with Answer and Explanation

Bacteria are prokaryotes that primarily reproduce asexually through binary fission, where a single cell divides into two identical daughter cells. Fungi are eukaryotes characterized by having cell walls primarily composed of chitin, a tough polysaccharide. Viruses lack cellular structure and metabolic machinery; they are obligate parasites that rely entirely on the host cell's machinery for replication. Thus, statements 1 and 3 are correct.
