(1)Based On development. (A)Pro meri stem. *It represent primary stage*plant embryonic axis represent*Give rise to primary meri stem. (B)Primary Meristem. *Originate from pro meristem.*Divided into different planes*Always in active stage division. Secondary Meri stem. *Originate from primary permanent tissue.*Give rise to secondary permanent tissue.*Cambium and Cork Cambium. (2)Based on Position. (A)Apical Meristem. *Tips of root and shoot.*Divided into different planes.*It help to increase length. (B)Lateral Meri stem. *Present in lateral side*Divide periclinelly.*Increase in thickness width of secondary growth. (C) Intercalary Meristem. *Found between permanent tissue.*It help to elongate body*It increase length from leaf base. (3)Based on planes of division. (A)Mass Meri stem. *Divide in all planes e.g endosperm.*From a mass of cell. (B) Rib Meri stem. *Divide in single plane*Form a row of cell e.g cortex (C) Plate Meri Stem. Divide into two plane.*Form a plate of cell. (4) Based of functon. (A)Protoderm. Develop epidermal cell pro cambium.

Develop epidermal cell pro cambium. (B)Pro Cambium. Develop primary vascular bundle. (C) Ground Meristem. At the end develop into width and cortex.
That chart is really helpful in distinguishing different types of meristems.
BTW
Thanks for sharing.
