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!

The reference point = a object used for comparison to determine if something is in motion.
An object is in motion if it changes position relative to a reference point.
You assume that the reference point is stationary, or not moving.
