Which level of organization is characterized by a group of cells that work together to perform a common function

Hey there! :D

Organization in organisms is like this:

cells => tissues => organs => organ systems => organisms

Since we are talking about a group of cells, this would be a tissue. Don't let the word 'function' confuse you. Tissues do functions as well as an entire organ or organ system.

It is helpful to use the flow chart when asked questions like these, so make sure to memorize it! It will be helpful in any level of science.

I hope this helps!
