Why do plants grow?

Because they need more leaves to carry out photosynthesis and create food, which can be converted into energy via respiration(which is NOT the intake of air!).

The growth of plants can be understood as an evolutionary result. Plants that fail to grow will not succeed either in surviving, or in reproducing, therefore that species will die out rapidly. The process of natural selection will favor plants that do grow. That's why plants grow.
