In multicellular organisms, several cells are grouped to form tissues. These tissues perform particular function at a definite place in the body. For example, nerve cells from the nervous tissue which helps in transmission of messages. This is known as division of labour in multicellular organisms. Because of this division of labour, multicellular organisms are able to perform all functions perfectly.

Tissue is nothing its only a group of working cells its needed because one single cell canot funtion to perform a even a single work ao cell has to combine to form a tissue.

Utility of Tissues in Multicellular Organisms
Tissues are groups of similar cells that work together to perform a specific function in an organism. In multicellular organisms, tissues play a crucial role in maintaining the overall structure and function of the organism. Below are some key points highlighting the utility of tissues:

Specialized Functions:
- Tissues allow for the division of labor within an organism, where different tissues specialize in carrying out specific functions. For example, muscle tissues are specialized for contraction and movement, while nerve tissues are specialized for transmitting signals.

Efficient Communication:
- Tissues enable efficient communication and coordination between different parts of the organism. For instance, nerve tissues help in transmitting signals from the brain to various parts of the body, allowing for quick responses to stimuli.

Support and Structure:
- Some tissues, such as connective tissues, provide support and structure to the organism. These tissues help in holding organs in place and providing a framework for the body.

Protection:
- Epithelial tissues form protective layers that cover the surfaces of organs and protect them from damage and infection. This helps in maintaining the integrity of the organism.

Regulation of Body Functions:
- Tissues such as glandular tissues help in the regulation of various body functions by producing hormones and other signaling molecules. These molecules play a crucial role in maintaining homeostasis within the organism.
In conclusion, tissues are essential components of multicellular organisms as they allow for specialization, communication, support, protection, and regulation of body functions. By working together, different tissues ensure the proper functioning and survival of the organism.
