The Cell Theory is a fundamental principle in biology that states that all living organisms are composed of cells, cells are the basic unit of structure and function in living organisms, and all cells come from pre-existing cells. The question asks us to identify the organism that does not fit into the Cell Theory.
Option 1: Bacteria – Bacteria are unicellular organisms that consist of a single cell. They have a cell membrane, cytoplasm, and genetic material, adhering to the principles of the Cell Theory. Therefore, bacteria fit into the Cell Theory.
Option 2: Virus – Viruses are unique biological entities that are not considered living organisms. They are acellular particles consisting of genetic material (DNA or RNA) surrounded by a protein coat. They do not possess a cellular structure and do not meet the criteria of being a cell. Therefore, viruses do not fit into the Cell Theory.
Option 3: Fungi – Fungi consist of multicellular organisms made up of eukaryotic cells. They have cell membranes, nuclei, and other cellular components, adhering to the principles of the Cell Theory. Therefore, fungi fit into the Cell Theory.
Based on this analysis, the correct answer is option 2, virus. Viruses do not fit into
