PPT-Single Celled Organisms

Unicellular Organisms Some organisms are made up of only one cell We call these organisms unicellular which means onecelled These organisms are much simpler than most organisms that are made up of many cells. Reptiles are a common example of a cold blooded organism with which most people are familiar If you have ever seen a lizard or snake in the early morning when the air and ground are cool you may have noticed how slowly they move They move slow when DiseasePathogenicagentlorisinaeotherprosimiansSimians, humans;primates ingeneral; otherspeciesSymptomsDetection /identificationTreatmentSource of infection /Prevention Loris and related species: healt What is a single-celled organism?.

Learning outcomes. Students should be able to understand the following:. How single-celled organisms exchange gases. How terrestrial insects balance the need to exchange gases with the need to conserve water.

The information our group researched is important because it tells us whether terrestrial or aquatic organisms have more mercury. Mercury can also kill many people. According to the EPA, mercury can be found in air, water and soil. Mercury is everywhere and it gets there by emissions from vehicles and emissions from factories, but the main ways are through .
