20. Phloem

         This is a picture of a tree trunk. This is an example of phloem. Phloem is the tissue in vascular plants that transport sugar and nutrients throughout the plant. In a tree, the phloem is located in the trunk between the cambium and the tree’s bark. All trees, as well as other vascular plants, need phloem to survive because that is how all parts of the plant get the needed nutrients to grow. There is phloem in the tree trunk because the tree needs to supply the food made in the leaves leaves to the rest of the tree, and the tree does so by transporting the food through the phloem in the trunk.
