Plant tropisms and growth hormones 

Introduction:

Look at the picture. Why are all pansy flowers faced the same direction? I checked them in the morning, noon time and even in the afternoon. It seems they are all looking at the sun. 

Even though I first noticed that in the Pansy flowers, it is not limited to pansies and viola. All flowers move. Some are just more noticeable.

When I first noticed such a movement, I simply thought plants are smart and will decide which way to face. Later I thought it might be the power of the sun that makes them move. But now I want to find out real reasons behind such peculiar movement.

 
 Project description:
In this project you study plant movements caused by environmental factors such as light and gravity. You will perform experiments to test the effect of each factor and you may also compare the effectiveness of each factor on plant movements.
