Match List I with List IIList I: a) Cells with active cell division capacity b) Tissue having all cells similar in structure and function c) Tissue having different types of cells d) Dead cells with highly thickened walls and narrow lumen List II: (i) Vascular tissues (ii) Meristematic tissue (iii) Sclereids (iv) Simple tissue

Answer & NCERT explanation

Correct answer: A -(ii), (b)-(iv), (c)-(i), (d)-(iii)

Meristematic tissue has cells with active cell division capacity. Simple tissue has all cells similar in structure and function (like parenchyma, collenchyma, sclerenchyma). Vascular tissues are complex tissues with different cell types (xylem and phloem). Sclereids are dead sclerenchymatous cells with thick walls and narrow lumen. NCERT Chapter 6 clearly defines these tissue types.

You can very easily see the structural similarities and variations in the external morphology of the larger living organism, both plants and animals. Similarly, if we were to study the internal structure, one finds several similarities as well as differences. This chapter introduces you to the internal structure and functional organisation of higher plants. Study of internal structure of plants is called anatomy. Plants have cells as the basic unit, cells are organised into tissues and in turn the tissues are organised into organs. Different organs in a plant show differences in their internal structure. Within angiosperms, the monocots and dicots are also seen to be anatomically different. Internal structures also show adaptations to diverse environments.

How NTA Uses This Concept

NTA tests the hierarchical organization of plant structures: cells → tissues → organs. Students often confuse tissue types (dermal, ground, vascular) or forget that different organs have different internal structures despite being made of the same tissues. The key trap is mixing up monocot vs. dicot anatomy—monocots have scattered vascular bundles while dicots have ring-arranged bundles; this distinction appears in cross-section diagrams. Remember: organization is hierarchical (smallest to largest), monocots and dicots differ structurally, and internal anatomy reflects environmental adaptation. Visual recognition of tissue arrangements in cross-sections is crucial for NEET.
