Question

Draw a cross-section of of a tree trunk, on it, label the xylem (tracheids), phloem, and the cambium (stem cells). For the tracheids, label which tracheids are most likely still functional (able to transport water) and which ones are most likely not functional (have air in the trachieds).  Also, write two sentence about the tree rings answering why the tree rings are formed and what scientists can use this information for. 

Answer 1

SOLUTION → The required diagram is: Epidermis Corkcambium » Cortex S A Porimary phloem y Secondevry phloem the vascular cambium & secondary xylem I pith Primary xylem → Xylem helps in transport of water through the vascular plants → Tree rings found in the bark of the tree are known as annual grouth rings which shows the amount of wood produced during one growing season. .. It is used by the scientists to determine the age of the tree by calculating the number of rings
