It is located near the node in some plants.
Explanation
Plant tissues are broadly classified into Meristematic tissues (actively dividing) and Permanent tissues (non-dividing). Meristematic tissues are further categorized based on their location in the plant body: Apical, Intercalary, and Lateral meristems.
Statement-wise Analysis:
- It is responsible for the increase in the length of the root. is Incorrect: The increase in the length of the root and shoot tips is the primary function of the Apical Meristem, which is located at the growing apices.
- It is located near the node in some plants. is Correct: The Intercalary Meristem is located between mature tissues, typically at the base of leaves or internodes (e.g., in grasses and bamboo). It is responsible for the elongation of internodes and the regeneration of parts removed by grazing herbivores.
- It forms the bark of the tree. is Incorrect: The bark of a tree is formed during secondary growth, which is driven by the Lateral Meristem (specifically the cork cambium), not the intercalary meristem.
- It is a type of permanent tissue. is Incorrect: Intercalary meristem is a type of Meristematic tissue, meaning its cells are capable of active cell division. Permanent tissues are formed when meristematic cells lose the ability to divide and differentiate into specific roles.
Key Takeaway:
Intercalary meristems are distinct from apical meristems as they are separated from the apex by permanent tissues and are primarily responsible for the elongation of internodes in monocots.
