Answer Sheet Notes (answers in bold)

How do plants respond to their environment?

Plants are sensitive to their environment and can respond to it. For plant roots to grow downwards they must grow towards gravity which directs it towards the water and minerals that the roots need to absorb. For plant shoots to grow upwards they must grow towards the light and against the force of gravity .This allows them to absorb more light so they can photosynthesis as much as possible.

The response of a plant to light is called phototropism.

The response of a plant to gravity is called gravitropism.

What causes the roots and shoots to grow in a particular direction, to bend?

If one side of a root or shoot…
