Question

which sequence accurately reflects the hierarchy of organization from the simplest to the most complex?
o systems → cells → tissues → organs
o cells → organs → tissues → systems
o cells → tissues → organs → systems
o systems → organs → tissues → cells

Explanation:

In biological organization, cells are the basic unit. Groups of similar cells form tissues. Different tissues working together make up organs. Multiple organs collaborating form an organ - system. So the correct order from simplest to most complex is cells → tissues → organs → systems.

Answer:

cells → tissues → organs → systems
