The center of a tree or shrub stem (from roots to trunk, branches, and twigs) is woody, composed of xylem cells that conduct water from the roots to the upper parts of the tree. That woody section is ...

The phloem in many trees is confined to a narrow layer near the periphery, so that it is possible to cut this channel completely by removing a narrow strip of tissue from the outside of the stem ...

We study genes that contribute to cell division activity in vascular cambium, the meristem between xylem (wood) and phloem. Understanding the regulation of the cambium activity enhancing factors might ...

Vascular cambium produces xylem (wood) and phloem, and together with the cork cambium ... and microscopy with molecular genetics to understand growth dynamics of the stem cells of the vascular cambium ...

Xylem cell They transport water and minerals up the stem to leaves and flowers ... Their walls contain lignin for strengthening. Phloem cell They transport sugars, amino acids, other substances ...

As water travels through the xylem in the stem and leaf, it is being replaced ... The sucrose is transported around the plant in phloem vessels. It needs to be able to reach all cells in the ...
