What is the utility of tissues in multicellular organisms?

Tissues are the building blocks of complex life in multicellular organisms. They offer two key benefits:

  • Division of Labor: Tissues consist of groups of similar cells that work together for a specific function. For instance, muscle tissue facilitates movement, while nervous tissue transmits signals. This specialization allows different parts of the organism to perform distinct tasks, much more efficiently than if all cells were the same.
  • Structure and Support: Different tissues provide structure and support to the organism. Bone tissue offers rigidity, while epithelial tissue forms the protective outer layer of the skin. This creates a well-organized and functional body.

In essence, tissues create a hierarchical organization within an organism, enabling complex functions and overall survival.
