Top Structural Organisation Questions for NEET
The topic of Structural Organisation in Animals and Plants is one of the most scoring and concept-driven sections in NEET Biology. Every year, multiple questions are directly picked from NCERT lines, diagrams, and definitions, making this chapter extremely high-yield. In this article on Top 5 Structural Organisation Questions, we will break down the most important previous year questions (PYQs), explain the core concepts behind them, and help you master this chapter with clarity.
If you are preparing seriously, this guide on Structural Organisation Questions will not only help you revise faster but also strengthen your NCERT-based accuracy.
Why Structural Organisation is Important for NEET
The chapter covers Morphology of Plants, Anatomy of Plants, Structural Organisation in Animals, and Animal Tissues. Questions are mostly direct, diagram-based, or concept-based. NEET frequently tests your understanding of tissue types, plant anatomy, and cockroach morphology.
A smart preparation strategy for Top 5 Structural Organisation Questions includes:
- Strong NCERT reading (line-by-line)
- Diagram practice
- Concept clarity over memorization
Top 5 Structural Organisation Questions (With Detailed Explanation)
Question 1: Which tissue is responsible for secondary growth in plants?
Options:
A. Apical meristem
B. Intercalary meristem
C. Lateral meristem
D. Permanent tissue
Correct Answer: C. Lateral meristem
Explanation:
Secondary growth in plants refers to the increase in girth or thickness. This growth is brought about by lateral meristems such as vascular cambium and cork cambium. Apical meristem contributes to primary growth (increase in length), while intercalary meristem helps in elongation in grasses.
This question from Top 5 Structural Organisation Questions highlights the importance of understanding plant growth regions.
Question 2: Which type of epithelium lines the alveoli of lungs?
Options:
A. Cuboidal epithelium
B. Columnar epithelium
C. Squamous epithelium
D. Ciliated epithelium
Correct Answer: C. Squamous epithelium
Explanation:
Alveoli require a thin lining for efficient gas exchange. Simple squamous epithelium provides a minimal barrier, allowing oxygen and carbon dioxide to diffuse easily.
In Top 5 Structural Organisation Questions, such questions test your understanding of structure-function relationships in tissues.
Question 3: Identify the correct statement regarding collenchyma.
Options:
A. Cells are dead with thick lignified walls
B. Cells are living with unevenly thickened walls
C. Cells lack cell walls
D. Cells are involved in transport
Correct Answer: B. Cells are living with unevenly thickened walls
Explanation:
Collenchyma provides mechanical support and flexibility to growing plant parts. The uneven thickening is due to cellulose and pectin deposition.
This is a frequently repeated concept in Top 5 Structural Organisation Questions, especially from plant tissues.
Question 4: Which part of cockroach is responsible for excretion?
Options:
A. Malpighian tubules
B. Nephridia
C. Green glands
D. Flame cells
Correct Answer: A. Malpighian tubules
Explanation:
In cockroaches, Malpighian tubules help in excretion and osmoregulation. They remove nitrogenous waste and regulate water balance.
Cockroach morphology is a goldmine for NEET, and questions like these are standard in Top 5 Structural Organisation Questions.
Question 5: What is the function of xylem?
Options:
A. Transport of food
B. Transport of water and minerals
C. Photosynthesis
D. Storage
Correct Answer: B. Transport of water and minerals
Explanation:
Xylem transports water and dissolved minerals from roots to aerial parts. It consists of tracheids, vessels, xylem parenchyma, and fibers.
Among all Top 5 Structural Organisation Questions, this is one of the most basic yet frequently asked concepts.
