Here's why:
* Living cells: The cambium layer, which is responsible for the growth of the bamboo stalk, contains living cells. These cells divide and differentiate to form new vascular tissues (xylem and phloem) that transport water and nutrients.
* Dead cells: The majority of the bamboo stalk is made up of dead cells, primarily xylem cells. These cells have thickened cell walls and are responsible for providing structural support.
So, while the bamboo stalk itself is primarily composed of dead cells, it relies on living cells in the cambium layer to continue growing and functioning.
