Remember the primary function of meristematic tissues: Apical grows the 'length' (primary growth), while Lateral grows the 'thickness' or 'width' (secondary growth).

Analyze the first pair relationship
Apical Meristem is the plant tissue located at the tips of shoots and roots responsible for primary growth, which is an increase in length.
Identify the function of the second term
Lateral Meristem (like vascular cambium) is responsible for secondary growth in plants, which results in an increase in the diameter or girth of the plant stem and roots.
A: Tips of stems is where Apical Meristem is located, not the function of Lateral Meristem. B: Nodes are points of leaf attachment, unrelated to the function of lateral meristem. D: Cell differentiation is a general process, not a specific functional outcome like girth increase.
C is correct because Lateral Meristem is responsible for increasing the secondary thickness of a plant stem, which is biologically referred to as Girth.
In biology-based analogies, always identify the 'Process vs Outcome' relationship. Here, the tissue is the 'Process/Agent' and the growth dimension is the 'Outcome'.
