There are three major classes of plant cells that can then differentiate to form the tissue structures of roots, stems, and leaves. (The three distinct types of plant cells are classified according to the structure of their cell walls and features of their protoplast.
Plants will have a primary cell wall and sometimes a secondary wall as well.
These two major parts are what determines the function of each individual plant cell.) The tissue types are: Dermal tissue - the outer most covering of a plant;
Vascular tissue - Responsible for transport of materials throughout the plant;
Ground tissue - Performs photosynthesis, starch storage and structural support.
