How do Plants grow?

Stored sugars are used to provide energy for the plant to grow and reproduce. An individual plant grows by cell division. The first plants reproduced asexually and later sexual reproduction evolved as a more efficient method of mixing the pool of genes. Cones or flowers contain a plant's sex organs. The colour scent and nectar of flowers are devices to attract pollinating insects and small animals. [CH] {TP}
