Question

What is the best example of tropism in plants

Answer 1

One example is hydrotropism.

If you pour water into soil, a plant's roots will grow towards the water.

Answer 2

Step-by-step explanation:

Some plants (flowers or leaves or both) follow the sun as it arcs across the sky each day; sunflowers (Figure below) are a well-known example. This behavior is misleadingly called heliotropism. Helio- does refer to the sun, but a tropism implies growth in a certain direction, and heliotropism does not involve growth.
