Short Answer Questions (3 Marks)

Q.1. What is the utility of tissues in multicellular organisms?

Ans: In multicellular organisms, tissues enable the division of labor among different cell groups. Specific functions are performed by different types of tissues, allowing complex processes to occur efficiently. For example, the brain controls bodily functions, the heart pumps blood, kidneys filter waste, and sense organs gather information. This specialization is essential for the organism's survival and proper functioning.
