Linnaean Classification of Living Organisms

Living organisms are sorted into groups based on shared features. These groups are arranged in a classification hierarchy. Refer to the table below. Which of the following pairs of organisms in the table are most closely related?

A student named Ava read about Carolus Linnaeus's classification system. She was interested to learn that domains had not been part of the Linnaean system. What is the value of Linnaeus’ system, and how is it applied today?

• The Linnaean system has been used for centuries and has eventually become so full that classifications need to be shortened.

• Even though it is an organized way to classify living things, it doesn’t allow for changes or new organisms. It had to be made into a new sort of classification system.

• Organisms are added continuously to the Linnaean system and it has been used to name, classify, and organize living things for centuries.

• The Linnaean system provided a way to organize and classify living things, and it has been changed over the years. With new ideas being added, this system is no longer used.

David and Henry are scientists working on classifying organisms based on their physical and biological characteristics. Which of the following tools would they need to determine how closely related two organisms are and to classify them accurately?

• A scale to weigh the mass of the organism

• An x-ray to examine the skeletons of the organisms

• A yardstick to measure the length of the organism

• a triple-beam balance to measure the weight of each of the organisms

Which of the following characteristics is NOT a feature of eukaryotic cells?

• Membrane-bound nucleus

• Absence of membrane-bound organelles

• DNA organized into chromosomes

• Larger size compared to prokaryotic cells

Lisa cannot determine an organism’s correct kingdom. She knows the organism is heterotrophic, eukaryotic, and multicellular. Based on these three characteristics, which of the following characteristics does Lisa need to know in order to identify the kingdom of the organism?

• Whether the organism has or doesn't have a cell wall.

• Whether the organism has or doesn't have golgi apparatus.

• Whether the organism has or doesn't have vacuoles.

• Whether or not the organism has fur.
