Grow Up, how?

Since gravity holds things down and is a pretty pwerful force, how is it things grow UPward? Especially something as fragile as a blade of grass?


I'm not asking about the direction of growth. I'm asking about the energy or force that allows grow to move against gravity.

    Gravity is the weakest force, considering Electromagnetism, Nuclear Binding Energy, etc.

    Everything developed considering gravity. If we moved to a planet with twice the gravity pull as Earth, the inhabitants there would become shorter due to the pull. Earth grass would probably not be able to grow.

    We're accustomed to this gravity so we grow.

    Gravity is actually a pretty weak force. Just look at magnetism in comparison, a tiny magnet has more force to hold itself to a refrigerator than the earth pulling on it.

    Check this wikipedia article that tells the four fundamental forces and how Gravity is by far the weakest:
