The plantae kingdom has more than 250,000 species, according to Palomar College. In many environments, these free-living protists are among the most important bacterium eaters and contribute to species diversity. These organisms are eukaryotic, and use sexual reproduction as part of their life cycle (instead of binary fission or other forms of asexual reproduction). Domains encompass an even larger section of life than kingdoms do. Many plant-like protists, for example, are autotrophic, meaning they generate their own energy through photosynthesis, much like plants. Plant and fungi organisms contain cell walls that are different in composition than bacteria. Match each component of the biosphere to benefits it provides for humans and other living organisms. She earned her PhD in Genetics from Indiana University. In summary, the three domains of life are: In the diagram below, the domains Prokarya (Bacteria), Archaea, and Eukarya are illustrated and differentiated.
