q.What two domain types have specific rod,spherical,or spiral shapes, multiply through bionary fusion and move by means of a flagellum? a. Bacteria and Archaea.
q. Unlike Bacteria which have a rigid cell wall, Archaea have chemical compositions of cell wall which differ from the other domains in what way? a. they are found in extreme environments, such as with salts and extreme temps.
q. All members of Eucarya domain are eukaryotic and are in three basic categories, what are they? a. Algae, Fungi and Protazoa.
q. Which of the Eucarya include single and multicellular organisms and have rigid cell walls and chlorophyll? a. Algae
q. Which of the Eucarya are both single celled(yeast) and multicellular(molds) organisms that are mostly found on land and Gain energy from organic materials? a. Fungi.
