What is a tissue?

• A. A group of cells that performs a specialized function
• B. A structure of the body that contains a spine
• C. A group of bones
• D. A part of the lymphatic system

Answer: (A)

A tissue is a group of cells that work together to perform a specific function. The cells in a tissue share characteristics and organize into a unit that carries out a specialized task, such as muscle tissue contracting to produce movement, epithelial tissue lining surfaces, connective tissue providing support, or nervous tissue transmitting signals. The spine is a structure within the skeleton, made up of bones and other tissues, not a tissue itself. A collection of bones describes the skeletal system, not a tissue. The lymphatic system consists of organs and tissues within that system, but that reflects a system, not the general definition of tissue. So the description that matches is a group of cells that performs a specialized function.
