<span>Coconut milk is a liquid endosperm, and has been found to be a very significant enhancer of growth and proliferation of plant stem cell tissues in the culture. Cytokinins present in the cocnut milk are attributed to this effect. Cytokinins stimulate shoot initiation, root growth, cell division, and leaf senescence.</span><span />
        
                    
             
        
        
        
The answer is most likely "vascular system". Xylem tissue is a part of a plant's vascular system. Which is mostly responsiple for transportation (of water, food etc.) in a plant. The vascular system of plants is made of two tissues. One is Xylem and the other is Phloem. Phloem transports food from leaves to all other parts of the plant. And Xylem transports water and minerals (which are dissolved in the water) to the leaves. 
So if you remove the <u>Xylem</u> tissue from a plant, its vascular system will be affected.
