I am doing an experiment about onion root growing.

I had put an onion in different solutions of $C_{11} H_{22} O_1$ in H2O —with the root touching the water—: 0,1M; 0,2M; 0,3M; 0,4M; 0,5M.

The measurements tell me that the presence of $C_{11} H_{22} O_1$ in the solution inhibites the growing of the root.

Why happen this? The Sucrose affects root's mitosis? How?

Thank you!
