Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

Answer:
The amount of water given to the plants depends on the effect of how tall the plant can overall grow. For instance, if all twenty identical plants are being given the same amount of water, then they will grow all at equal rates. However, if there is not equal amount/consistency with the amount of water the plants receive, then this factor may contribute to an uneven growth pattern between all twenty plants. However, other factors (such as location, sunlight, etc.) may also contribute to a plant's growth.
