Organizations of similar cells
Correct Answer
D. Organizations of similar cellsExplanation
Tissues are organizations of similar cells. In the human body, different types of tissues work together to perform specific functions. These tissues are made up of cells that have similar structures and perform similar functions. For example, muscle tissue is made up of muscle cells that contract to produce movement. Epithelial tissue is made up of epithelial cells that line the surfaces of organs and protect underlying tissues. So, tissues can be defined as groups of cells that are similar in structure and function and work together to carry out specific tasks in the body.Rate this question:
