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!
they’re a product of sexual reproduction that are usually located on the lower surface of fern leaves. they’re essential for reproduction , they’re clusters of sporangia which contain the spores in plants like ferns & moss
So, I haven't really seen this question I think but in my class when we had science before we learned about Kinetic and Potential energy. So, my most best answer I can give is most likely Kinetic Energy. Sorry if it's wrong. Hope this helps! ^^
