hi i want to ask you what does a root do to help plants grow? and what does a leave do to help a plant grow? could you please answer this queastion immediately?

As I said to your later post, it is unrealistic to expect an immediate reply. However, you should typically get a reply within 24 hours, as most tutors check the message boards at least daily.

Since this is not my area of expertise, I searched Google under the key words "plant growth roots leaves" to get these possible sources:

http://www.life.umd.edu/classroom/bsci124/lec2.html
http://www.answers.com/topic/plant-growth

In the future, by using the appropriate key words, you can search yourself to get answers more quickly.

I hope this helps. Thanks for asking.

I am not a biologist or plant man but here is a non-scientific answer. Roots are the primary way plants derive nutrients and water from the soil. Leaves are how plants breathe and use sunshine in the process of photosynthesis to convert CO2 and H2O to starches (ultimately).
