Verified step by step guidance1
Understand the definition of tissues: Tissues are groups of cells that work together to perform specific functions in the body.
Recognize the two main components of tissues: Cells, which are the basic structural and functional units of life, and the extracellular matrix, which provides structural and biochemical support to the surrounding cells.
Clarify the role of cells: Cells in tissues are specialized for specific functions, such as muscle contraction, nerve signaling, or secretion.
Explain the extracellular matrix: The extracellular matrix is composed of proteins (like collagen and elastin) and other molecules (like glycoproteins and proteoglycans) that help maintain tissue structure and facilitate communication between cells.
Conclude that the correct answer is 'Cells and extracellular matrix,' as these are the fundamental components of all tissues in the body.
