Prokaryotes are organisms that do not have defined nuclei in their cells. Eukaryotes are organisms that have cells with membrane-bound nuclei.

In which of the following kingdoms are prokaryotes found?

• Eubacteria and Archaea only

• Eubacteria, Archaea, Protist, and Fungus only

• Plant and Animal only

• Protist, Fungus, Plant, and Animal only

The Linnaean system of classification uses a nested hierarchy to sort organisms into groups based on similarities and differences in their characteristics. The sequence is as follows;

kingdom > _______ > class > order > family > genus > species

What category belongs in the blank space above?

• phylum
• domain

• unicellular

• eukaryote

A cell is classified as eukaryotic if the cell

• contains a nucleus

• has a cell wall

• lives in the absence of oxygen

• contains chloroplasts

Why do scientists classify organisms?

• to determine relationships between organisms

• to more easily identify different kinds of organisms

• to have a systematic way of categorizing newly discovered organisms

• all of these

When organisms are classified, they are given a two-part name, such as Canis lupus for wolves and Felis catus for domestic cats. The first part of the name represents the genus of the organism. The second part of the name represents the organism's species. This naming system is known as:

• Newton's laws

• Linnaean taxonomy

• binomial nomenclature

• natural selection

Michelle wants to classify an organism that she is studying in lab. The organism is multicellular, makes its own food, and is unable to move around its environment. The organism that Michelle is studying can most likely be classified into Domain:

• Eukarya

• Animalia

• Bacteria

• Archaea

• It is where most of the organelles of the cell are located.

• all of these
