Which of the Following is the Highest Level of Organization

Question

Which of the following is the highest level of organization?
A) chemical
B) organelles
C) cellular
D) tissues
E) organs

Accepted Answer

Organs are formed from the combination of different tissues and are therefore a higher level of organization than tissues, which are made up of cells, and cellular and organelle levels, which are smaller components within cells. The chemical level is the smallest level of organization and is not comparable to the others in terms of complexity.
