Question: What is the utility of tissues in multicellular organisms class 9?
Tissues are collections of similar cells in multicellular organisms that are organized to perform specialized functions. They serve several essential roles in the body, including providing structure and support, facilitating communication and coordination between cells, transporting nutrients and fluids, and protecting the body from disease. By working together, these specialized cells can form complex structures and perform more sophisticated functions than individual cells on their own.
For example, the epithelial tissue that lines the digestive tract is essential for digestion, while muscle tissue enables us to move. Connective tissue helps to hold the body together, and nerve tissue is essential for sending and receiving signals between different parts of the body. By working together, these tissues help to maintain homeostasis in the body and carry out the physiological processes needed for sustained life.
