How are tissues defined?

1. Groups of organs working together

2. Groups of cells similar in structure and function

3. Groups of proteins that support muscles

4. Groups of bones forming a structure

The correct answer is: Groups of cells similar in structure and function

Tissues are defined as groups of cells that are similar in structure and function. This definition is fundamental in the study of anatomy and biology because tissues comprise the building blocks of organs and contribute to the overall functioning of the body. Each type of tissue serves distinct roles; for example, epithelial tissue covers surfaces and lines cavities, while connective tissue supports and binds other tissues. Understanding this classification allows for a deeper appreciation of how complex biological systems operate, as different tissues work together to form organs, which in turn form systems. This highlights the importance of cellular organization and specialization in maintaining health and functionality within living organisms.
