Unit 1 Test Review

Which answer choice best describes how cells, tissues, organs, and organ systems work together within a multicellular organism.

• They do not work together. They all work independently of one another.

• Cells make up tissues, tissues make up organs, organs make up organ systems, and organ systems make up organisms.

• Organisms work on their own with no help from any other organ system, organs, tissues or cells.

• Cells are not the building blocks for life, they play no part in helping the organism function as a whole.
