In the spring before the leaves come out,maple trees are often tapped to collect sap to make syrup.The sugars were stored in the wood of the tree as starch and then released as temperatures rise above freezing in late winter.The resulting sucrose is released into the vessels that transport water.Which of the following would a person tap to collect sap from a maple tree?

Xylem is the tissue responsible for transporting water and nutrients from the roots to the rest of the tree, including the photosynthetic tissues in the leaves. When a maple tree is tapped for sap, the hole is drilled into the xylem tissue, allowing the sap to flow out. Phloem, collenchyma tissue, and parenchymal tissue are not involved in the transport of sap and do not contain the high concentrations of sugar found in maple sap. Roots are also not typically used for sap collection as they are below ground and not easily accessible.
