(cell walls or nuclei) Chapter 9.2 DRW 3 9.2 continued Notes: Read the following section highlights. At first, living things were classified as either plants or animals. As scientists discovered more about living things and discovered more organisms, new kingdoms were added that were more descriptive than the old two-kingdom system. Most biologists recognize six kingdoms—Archaebacteria, Eubacteria, Protista, Plantae, Fungi, and Animalia. Bacteria are prokaryotes, single-celled organisms that do not contain nuclei. The organisms of all other kingdoms are eukaryotes, organisms that have cells with nuclei. Archaebacteria have been on Earth for about 3 billion years and can live where most other organisms cannot survive. Most bacteria are eubacteria and live almost everywhere. Some are harmful, and some are beneficial. Plants, most fungi, and animals are complex multicellular organisms. Plants perform photosynthesis. Fungi break down material outside their body and then absorb the nutrients. Animals eat food, which is digested inside their body. 1.
