Answer:
Plants are classified based on the presence of a certain specialized tissue. A specialized tissue called xylem tissue helps transport water and dissolved minerals to all parts of the plant.
Step-by-step explanation:
Xylem is a complex tissue in plants that is responsible for the transportation of water and dissolved minerals from the roots to the leaves and other parts of the plant. It is composed of several different cell types, including tracheary elements and parenchyma cells. The tracheary elements have thick walls and are dead at maturity, they are responsible for the transportation of water and dissolved minerals. The parenchyma cells support the tracheary elements and also store food.
Xylem is one of the two types of transport tissue in plants, the other one is called phloem, which is responsible for the transportation of sugars and other organic compounds throughout the plant.
