Prokaryotic {List at least 3 characteristics about prokaryotic cells} Eukaryotic {List at least 3 characteristics about eukaryotic cells} What is the main difference between a prokaryotic cell and a eukaryotic cell? 6.12C: Domains Biological taxonomy is the of life into. All organisms are grouped based on their. What are the three Domains and what kind of cells do they have? The broadest category organisms are classified into is known as After Domains, the next category is known as Organisms are placed into a Domain based on the presence or absence of a

Include the basic characteristics that classify cells into those Kingdoms. Bacteria Archaea Protista Fungi Plantae Animalia 6.12E: Biotic vs. Abiotic Factors Biotic Factors: The factors are the components of an ecosystem. o This also includes the the living organisms play within the ecosystem. List some biotic factors that might be found in an ecosystem? Abiotic Factors: The factors are the components of an ecosystem. o These factors affect living organisms and their ability to and. List some abiotic factors that might be found in an ecosystem?

Being heterotrophic or autotrophic d. Presence of a nucleus in cells 11. Distinguish between the terms autotroph and heterotroph. 8. An organism called Euglena is represented in the diagram. The Euglena can be classified as eukaryotic due to the presence of which labeled part? 12. A macaw is a type of parrot with colorful feathers that flies about in the upper canopy of trees in tropical rainforests. Macaws have a diet which includes fruits, leaves, nuts, and seeds of plants. Which of the following describes a biotic factor of the Macaw s habitat that provides a survival advantage for these birds? a. The colorful feathers are lost and regrow each year. b. Some rainforest predators are able to climb trees. c. Trees provide shelter and abundant food supplies. d. During some periods, rain falls nearly every day. 13. Identify the broadest taxonomic classification of living organisms. Name the groupings within this taxonomic classification. a. Part A, which allows the cell to turn sunlight into food. b. Part B, which allows the cell to move itself from place to place. c. Part C, which is centrally located and stores genetic material. d. Part D, which allows the organism to store water. 9.
