**Question:**

Using this magic, I'm wondering if it is possible to accelerate the growth of a plant. Can the cells of a plant (a tree for instance) be altered in such a way that a seedling could reach maturity in a matter of weeks? Days? Hours? Minutes even?

Remember that 'changing the cells' doesn't mean they now magically do what I want. The cells can only be *altered*, so that they produce different chemicals or perhaps react differently. The cells cannot be controlled or anything.

**Note:** Assume that the plant has access to unlimited amounts of energy as a byproduct of the magic.
