How to approach this question

Full Answer
A group of similar cells with a similar structure and function.
In biology, a tissue is defined as a group of similar cells that work together to perform a specific function. For example, muscle tissue is made of muscle cells that contract, and xylem tissue in plants is made of xylem cells that transport water.
Common mistakes
✗ Confusing tissue with an organ (e.g., "a group of tissues"). An organ is a group of different tissues working together.
✗ Just saying "a group of cells" without mentioning they are similar or have a common function.
