Which level of organization comes after tissue?

Which level of organization comes after tissue?

• A. Organ System
• B. Organ
• C. Cellular
• D. Chemical

Answer: (B)

The level after tissue is organ because tissues—groups of similar cells—come together to form organs, which are structures that perform specific, coordinated functions. For example, the heart is an organ made of muscle tissue, connective tissue, and other tissues that work in harmony to pump blood. After organs, the next level is organ systems, which coordinate multiple organs to carry out broader bodily tasks, and finally the organism as a whole. Other levels don’t fit here because cellular (cells form tissues), chemical (molecules and atoms), and organ system (beyond an organ) aren’t the next step after tissue.
