The vascular tissue responsible for transporting and distributing organic nutrients is referred to as phloem.
In addition to serving as a communication system, the phloem also serves as a structural component of the plant.
Sieve elements, parenchyma, and sclerenchyma are the three cell types that make it up.
Protophloem
The phloem that arises from procambium is made up of small, thin-walled cells and is frequently connected with a fast-growing region is called protophloem.
