Cambium is an example of

The correct answer is Lateral meristem

Concept:

• Meristematic tissues in plants are responsible for growth and are composed of cells that can divide actively.
• Meristems can be classified into three types based on their location: apical meristem, intercalary meristem, and lateral meristem.
• The cambium is a specific type of lateral meristem, primarily responsible for secondary growth, which increases the girth of roots and stems in plants.

Explanation:

Lateral Meristem:

• The cambium is an example of a lateral meristem. It is located along the sides of stems and roots.
• Its primary role is to facilitate secondary growth by producing new vascular tissues (xylem and phloem) and increasing the thickness (girth) of the plant.
• Examples of lateral meristems include vascular cambium and cork cambium.
• These meristems contribute to the formation of wood and bark in trees, making them vital for plant structural support and nutrient transport.

Other Options:

Apical Meristem:

• Located at the tips of roots and shoots, the apical meristem is responsible for primary growth, which increases the length of the plant.
• It helps in the formation of new leaves, flowers, and elongation of stems and roots.

Intercalary Meristem:

• Found at the base of leaves or internodes, the intercalary meristem is responsible for elongation and regrowth of certain parts of the plant, such as grass after grazing.

Permanent Tissue:

• Permanent tissues consist of cells that have lost the ability to divide and are specialized for specific functions like support, transport, or storage.
• Cambium, being meristematic, is actively dividing and hence cannot be classified as permanent tissue.
