Textbook Question
Fill in the blanks: Bacteria are ___________________ cells in the domain ___________________. In contrast, the domain ___________________ includes unicellular and multicellular organisms that are made of ___________________ cells, or cells that have a nucleus and membrane-bound organelles.
Verified step by step guidance1
Identify the type of cells bacteria are by recalling their cellular structure. Bacteria lack a nucleus and membrane-bound organelles, so they are classified as ___________________ cells.
Determine the domain to which bacteria belong. Bacteria are part of the domain ___________________, which includes prokaryotic organisms.
Recognize the domain that includes organisms with cells that have a nucleus and membrane-bound organelles. This domain is ___________________.
Understand that organisms in this domain can be unicellular or multicellular and are made of ___________________ cells, which are characterized by having a nucleus and membrane-bound organelles.
Fill in the blanks with the correct terms: Bacteria are ___________________ cells in the domain ___________________. In contrast, the domain ___________________ includes unicellular and multicellular organisms that are made of ___________________ cells.
