Question

why tree grow against gravity?

Answer 1

Because plants grow towards the sunlight, which is generally considered "up." Some plants also purposefully grow against gravity. Remember, gravity is not an unstoppable force- if it was, we couldn't walk on this Earth, or grow, or anything. Gravity on Earth pulls things towards the core but not so much that they can’t resist. Even then, plants have stems and many other supports to keep them standing, like roots. Sometimes plants are too inherently weak to grow very tall, and so they don't. Most grass, for example, could not grow very tall without leaning over or falling. It has a leafy stem, as opposed to a woody one in, say, a tree.
