stromatolites : a calcareous mound built up of layers of lime-secreting cyanobacteria and trapped sediment, found in Precambrian rocks as the earliest known fossils, and still being formed in lagoons in Australia
eukaryotes : an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus.
shield : generally a large area of exposed Precambrian crystalline igneous and high-grade metamorphic rocks that form tectonically stable areas
prokaryotes : a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles
photosynthesis : the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
