Yоu hаve been given fоur test tubes аnd аsked tо identify the protist species in each tube. Use the following information in your identification: Chemical analysis of test tube 1 indicates the presence of a chemical that is toxic to fish and humans. Chemical analysis of test tube 2 indicates the presence of substantial amounts of silica. Microscopic analysis of organisms in test tubes 1 and 3 reveals the presence of permanent, membrane-bounded sacs just under the plasma membrane. Microscopic analysis of organisms in test tube 3 reveals the presence of an apical complex in each. Microscopic analysis of the contents in test tubes 2 and 4 reveals the presence of flagella with hair-like projections on each organism. Chemical analysis of test tube 4 indicates the presence of a chemical capable of decomposing plant tissue. When light is shone on the tubes, oxygen bubbles accumulate on the inside of test tubes 1 and 2. Tube 1 [protist1] Tube 2 [protist2] Tube 3 [protist3] Tube 4 [protist4]
