NCERT Diagram Based Questions Part-2: NEET Guide

NCERT textbooks for NEET preparation often include diagrams, illustrations, and flowcharts that convey important concepts and processes in a visual manner. To excel in NEET, you need to practice understanding and interpreting such diagrams. Here are some tips and examples of NCERT diagram-based questions.

1. Understand the context and labels

Before trying to answer a diagram-based question, read the accompanying text or paragraph carefully to know what the diagram represents and what the labels or symbols mean. If necessary, refer to the glossary or index to check the meanings of unfamiliar terms. Pay attention to the units, scales, and directions indicated in the diagram.

Example:

The following diagram shows the process of photosynthesis in a typical plant cell.

What is the role of chlorophyll in this process?

2. Observe the structure and function

Once you understand the context and labels of a diagram, observe the structure and function of the depicted components or systems. Look for patterns, connections, and differences between them. Identify the key features and their roles in the process or phenomenon being illustrated.

Example:

The following diagram shows the structure of a neuron or nerve cell.

What are the main parts of a neuron and how do they transmit electrical impulses?

3. Analyze the changes and interactions

Some diagram-based questions may require you to analyze the changes or interactions that occur in a system or process over time or under different conditions. Look for arrows, curves, or other symbols that show the direction, rate, or magnitude of the changes. Compare the initial and final states or the effects of different factors on the system.

Example:

The following diagram shows the life cycle of a typical angiosperm or flowering plant.

What are the stages of the plant life cycle and how do they relate to seed production and dispersal?

4. Apply the concepts and principles

Finally, diagram-based questions may also test your ability to apply the concepts and principles learned from the text or lectures to new situations or scenarios. Use your knowledge of the relevant theories, laws, or models to explain the patterns or phenomena depicted in the diagram. Use examples, analogies, or diagrams to illustrate your answer.

Example:

The following diagram shows the energy flow in an ecosystem or food chain.

Explain how the laws of thermodynamics and the concept of trophic levels can help us understand the efficiency and stability of an ecosystem.

In summary, NCERT diagram-based questions in NEET require you to understand the context and labels, observe the structure and function, analyze the changes and interactions, and apply the concepts and principles. Practice solving such questions by reviewing the relevant chapters, drawing your own diagrams, and discussing with your peers or teachers.
