What is the difference between negative and positive phototropism? |
Positive phototropism grows towards the light Negative phototropism grows away from the light |
|
|
What is the difference between negative and positive geotropism? |
Positive geotropism grows towards the force of gravity Negative geotropism grows against the force of gravity |
|
|
What makes the root grow downwards towards gravity? |
The cells elongate causing the root to bury in the ground. |
|
|
Why is important for plants to grow towards the light? |
Its important because it means that the plant can get enough sunlight for it to photosynthesis and make energy/food to survive |
|
