leaves and roots

Answer 1

The main plant organs at work when a plant grows as mediated by growth hormones are primarily the **meristem and roots**. The meristematic tissues, which are found in regions like the tips of roots and shoots, are responsible for the growth of new cells, while roots play a vital role in nutrient and water uptake, contributing to overall growth.

So, the most accurate choice would be **meristem and roots**.
