Question

which phrase best describes a tissue?
a. group of specialized cells that have a similar function
b. group of tissues that differentiates at the same rate
c. group of tissues that performs a function
d. group of organs that work together

Explanation:

To determine the best description of a tissue, we recall the biological definition: a tissue is a group of specialized cells with a similar structure and function.

• Option A: Matches the definition of a tissue (group of specialized cells with similar function).
• Option B: A group of tissues would be an organ system or organ, and "differentiates at the same rate" is not relevant to tissue definition.
• Option C: A group of tissues is not a tissue; a tissue is made of cells, not other tissues.
• Option D: A group of organs working together is an organ system, not a tissue.

Answer:

A. group of specialized cells that have a similar function
