Which kingdom of Eukarya consists primarily of unicellular organisms? Plantae Fungi Animalia Protista Question 8 of 20 A researcher collected archaea and protists from a thermal vent. How do the cells of these two organisms differ? Protist cells will contain organelles. Protist cells will contain DNA. Archaea cells will contain nuclei. Archaea cells will be larger. Question 9 of 20 What is one mechanism of evolution? Adaptation

as yeasts and molds (British English: moulds)‚ as well as the more familiar mushrooms. These organisms are classified as a kingdom‚ Fungi‚ which is separate from plants‚ animals‚ protists and bacteria. One major difference is that fungal cells have cell walls that contain chitin‚ unlike the cell walls of plants and some protists‚ which contain cellulose‚ and unlike the cell walls of bacteria. These and other differences show that the fungi form a single group of related organisms‚ named the Eumycota (true

genetic copies of the parent. A more stringent definition is agamogenesis which is reproduction without the fusion of gametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea‚bacteria‚ and protists. Many plants and fungi reproduce asexually as well. While all prokaryotes reproduce asexually (without the formation and fusion of gametes)‚ mechanisms for lateral gene transfer such as conjugation‚ transformation and transduction are sometimes likened

nuclear envelope‚ the association of DNA with histone proteins and its organization into a number off distinct chromosomes‚ and complex organelles‚ among which are chloroplasts and mitochondria. Scientists believe that eukaryotic organisms such as the protists evolved from the prokaryotes. There are two main theories which describe how this transition may have occurred. The first is the endosymbiotic theory‚ or enosymbiosis‚ and the other is the autogenous theory‚ or autogenisis. These two theories
