Question

Which option shows the correct order of organization within multicellular organisms ( from least complex to most complex )?

Cell - Tissue - organ system - organism

Cell - organ - organ system - organism - cell

organ - organ system - cell - organism - tissue

Answer 1

The correct order of organization within multicellular organisms from least complex to most complex is:

**Cell - Tissue - Organ - Organ System - Organism**

However, since this exact sequence isn't represented in your options, the closest option that makes sense is:

**Cell - Tissue - organ system - organism**

This option includes "organ" implicitly within "organ system," which is the closest to the correct hierarchy.
