Question

which list represents the levels of organization in a multicellular organism from the simplest level to the most complex level? 2 points
○ cell, organ, tissue, organ system
○ organ system, organ, tissue, cell
○ tissue, organ, organ system
○ cell, tissue, organ, organ system

Explanation:

To determine the correct order of levels of organization in a multicellular organism, we recall the biological hierarchy: Cells are the basic unit of life. Groups of similar cells form tissues. Tissues combine to form organs, and organs work together in organ systems. Let's analyze each option:

• First option: Incorrect order (organ comes after tissue, not before).
• Second option: Reverse order (starts from complex to simple).
• Third option: Missing the cell level (the simplest level).
• Fourth option: Follows the correct sequence: cell (simplest) → tissue (group of cells) → organ (group of tissues) → organ system (group of organs, most complex).

Answer:

D. cell, tissue, organ, organ system (assuming the last option is labeled D; if the original labels were different, adjust the identifier, but the text is "cell, tissue, organ, organ system")
