Multiple Choice

Which of the following correctly lists the levels of organization in an organism from simplest to most complex?

Organism, Organ System, Organ, Tissue, Cell

Organ System, Organism, Organ, Tissue, Cell

Tissue, Cell, Organ, Organ System, Organism

Cell, Tissue, Organ, Organ System, Organism

Verified step by step guidance

Understand that biological organization in organisms is hierarchical, meaning it progresses from simpler to more complex structures.

Identify the simplest level of organization, which is the 'Cell'. Cells are the basic structural and functional units of life.

Recognize that 'Tissues' are the next level, formed by groups of similar cells working together to perform a specific function.

Acknowledge that 'Organs' are composed of multiple tissue types that work together to perform specific functions within the body.

Understand that 'Organ Systems' consist of different organs that collaborate to carry out complex functions necessary for the organism's survival.

Finally, recognize that the 'Organism' is the most complex level, representing the complete living entity capable of independent existence.
