Difference between Primary and Secondary Meristem

Primary vs Secondary Meristem in Plants

Primary Meristem vs Secondary Meristem
(Similarities and Differences between Primary and Secondary Meristem)

Meristems are a group of plant cells that remain in a continuous state of division. The meristematic cells continuously produce new cells through the life of the plant. In previous posts, we have discussed the Characteristics of Meristematic Cells, Classification of Meristems and Difference between Meristematic and Permanent Tissues.

Meristems are classified into different categories based on different criterions. In one such classification, the meristems are classified into two groups based on the nature of cells giving them. These two groups are (1) Primary Meristem and (2) Secondary Meristem.

(1). Primary Meristem: Primary meristems are the direct descendants of the embryonic cells. They continuously involved in the cell division and growth process of the plant. Example: apical meristem of shoot apex and root apex.

(2). Secondary Meristem: Secondary meristems are the meristematic tissue arises from the permanent tissues. Secondary meristems are usually lateral meristems and are responsible for the increase in thickness of the plant. Example: vascular cambium and cork cambium (phellogen).

The present post describes the Similarities and Differences between the Primary Meristem and Secondary Meristem.
