WebbPhloem mostly contains sugar molecules dissolved in water forming a very thick sugary sap, which is food for them. And if you're wondering what these things are over here at the sides, that is some leftover cytoplasm. The cells don't lose all of their cytoplasm. And similarly, this is the cell walls. They have developed gaps in between. circle pottery stokeWebbBark – main function is to protect the living tissue called cambium from damage. Roots – two main functions: (1) collect nutrients and water and (2) anchor the tree.
