Formation of tissues leads to
Increased efficiency of functioning
Delegation of metabolic activities
Both a and b
None of these
The formation of tissues in multicellular organisms leads to increased efficiency of functioning. Tissues are specialized groups of cells that work together to perform specific functions. This division of labor allows cells to specialize in particular tasks, leading to more efficient and effective biological processes. Different tissues have specific functions, such as support, movement, electrical signaling, and biochemical processes. By organizing into tissues, cells can optimize their roles and contribute to the overall efficiency of the organism's functioning.
Hence, option 1 is the correct answer.
