Final answer:
It is true that cake pans should be greased from the bottom to the sides to prevent sticking. This assists in even rising and easy removal of the cake after baking.
Step-by-step explanation:
True: Cake pans should be greased from the bottom up to the sides to prevent the cake from sticking. Prior to baking, it is important to prepare the cake pan to ensure that the cake can be easily removed after it's baked. Typically, you would use butter, cooking spray, or oil to lightly coat the bottom and all sides of the pan. Some recipes also suggest dusting the greased pan with a bit of flour to further prevent sticking. This method helps the cake to rise evenly and prevents the edges from getting stuck, which could cause the cake to tear when you try to remove it from the pan.
