hi , i have a worksheet and i need some help. Its hard to explain because i had a worksheet with a diagram .. but here goes! i will be very grateful for some help!!!!

Some students set up an apparatus. Flask A has a water inside it and a plant. The top of the flask is being blocked off with some cotton wool. The same for Flask B however , there is not plant in Flask B. After 24 Hours the mass in Flask b has changed but the mass in flask a has stayed the same. Why does this happen?
