What type of meristem is formed from the differentiation of permanent tissues such as cambium?

The correct answer is related to the type of meristem that develops from the differentiation of permanent tissues. Lateral meristems are responsible for the secondary growth in plants, contributing to an increase in girth. They arise from previously differentiated tissues, such as cambium, which is a layer of actively dividing cells located between the xylem and phloem.

Lateral meristems include vascular cambium and cork cambium, both of which play crucial roles in producing new vascular tissues and protective outer layers, respectively. This is essential for the growth of woody plants, allowing them to increase in thickness and to enhance their structural integrity over time.

Other types of meristems, such as apical meristems, are located at the tips of roots and shoots, and they facilitate primary growth, leading to an increase in height rather than girth. The terms eumeristems and pseudomeristems are not commonly used in the context of established plant tissue development and do not pertain to the differentiation from permanent tissues. Therefore, lateral meristems are the appropriate answer for this question.
