It's produced by one part of the body and is then transported to other parts of the body, where it triggers responses in cells and tissues.

If you rotate the plant, it will soon reorient its growth until its leaves again face the window.  (Hello, everybody!  Could you have a look for me at the word "reorient"?  What does it mean in this sentence?  I can not get it.  I do not understand this word and this sentence, could you make it clearer for me to get it?  Thanks a lot !)   The growth of a plant toward light is called "phototropism". ... ...

	Clive  +  650885 Thu, 22 Jan 09 01:32 AM Hi, The plant is growing towards the window. You turn it around, so that it is growing away from the window.

According to what you said, then in the context above, "reorient its growth" actually refers to "reorient the direction of its growth", right? IMPSX-EF Context, Plants
