Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

In cellular respiration, the organic compounds that are oxidized to release energy within living cells are called respiratory substrates. Usually, which of the following serves as the primary and most common respiratory substrate?

कोशिकीय श्वसन में, सजीव कोशिकाओं के भीतर ऊर्जा मुक्त करने के लिए ऑक्सीकृत होने वाले कार्बनिक यौगिकों को श्वसनी क्रियाधार (respiratory substrates) कहा जाता है। आमतौर पर, निम्नलिखित में से कौन प्राथमिक और सबसे आम श्वसनी क्रियाधार के रूप में कार्य करता है?

Glucose (Carbohydrates)ग्लूकोज (कार्बोहाइड्रेट)

Triglycerides (Fats)ट्राइग्लिसराइड्स (वसा)

Keratin (Proteins)किरेटिन (प्रोटीन)

Organic acids like malateमैलेट जैसे कार्बनिक अम्ल

Correct Answer: Option A

Explanation:

NCERT Section 14.1 states: 'Usually carbohydrates are oxidised to release energy, but proteins, fats and even organic acids can be used as respiratory substances in some plants, under certain conditions.' Glucose is the favored substrate.

NCERT अनुभाग 14.1 में कहा गया है: 'आमतौर पर ऊर्जा मुक्त करने के लिए कार्बोहाइड्रेट ऑक्सीकृत होते हैं, लेकिन कुछ पौधों में कुछ विशेष परिस्थितियों में प्रोटीन, वसा और कार्बनिक अम्ल भी श्वसनी पदार्थों के रूप में उपयोग किए जा सकते हैं।' ग्लूकोज पसंदीदा क्रियाधार है।

Plants, unlike animals, have no specialized organs for gaseous exchange like lungs or gills. Which of the following reasons given by NCERT explains why plants can get along without specialized respiratory organs?

जंतुओं के विपरीत, पौधों में फेफड़े या गलफड़ों जैसे गैस विनिमय के लिए कोई विशेष अंग नहीं होते हैं। NCERT द्वारा दिया गया निम्नलिखित में से कौन सा कारण बताता है कि पौधे विशेष श्वसन अंगों के बिना भी अपना कार्य कैसे चला लेते हैं?

Plants consume oxygen at a rate much higher than animals, which creates strong suction pressure.पौधे जंतुओं की तुलना में बहुत अधिक दर से ऑक्सीजन का उपभोग करते हैं, जिससे तीव्र चूषण दाब बनता है।

Each plant part takes care of its own gas-exchange needs, and there is very little transport of gases from one part to another.पौधे का प्रत्येक भाग अपनी गैस-विनिमय आवश्यकताओं की स्वयं देखभाल करता है, और एक भाग से दूसरे भाग में गैसों का बहुत कम परिवहन होता है।

Plant cells are tightly packed without any intercellular spaces, preventing gases from diffusing out.पादप कोशिकाएं बिना किसी अंतरकोशिकीय स्थान के आपस में सटी होती हैं, जिससे गैसें बाहर नहीं विसरित हो पातीं।

Photosynthesis permanently eliminates the need for any cellular respiration in all green plant cells.प्रकाश संश्लेषण सभी हरी पादप कोशिकाओं में किसी भी कोशिकीय श्वसन की आवश्यकता को स्थायी रूप से समाप्त कर देता है।

Correct Answer: Option B

Explanation:

NCERT gives three reasons why plants lack specialized respiratory organs: (1) each plant part takes care of its own gas-exchange needs with minimal gas transport between parts, (2) plants do not present great demands for gas exchange (far lower respiration rates than animals), and (3) living cells are located close to the plant surface and are loosely packed with interconnected air spaces.

NCERT तीन कारण बताता है कि पौधों में विशेष श्वसन अंगों का अभाव क्यों होता है: (1) पौधे का प्रत्येक भाग अपनी स्वयं की गैस-विनिमय आवश्यकताओं की देखभाल करता है और भागों के बीच गैसों का बहुत कम परिवहन होता है, (2) पौधों में गैस विनिमय की अत्यधिक मांग नहीं होती है (जंतुओं की तुलना में बहुत कम श्वसन दर), और (3) जीवित कोशिकाएं पौधे की सतह के निकट स्थित होती हैं और परस्पर जुड़े वायु स्थानों के साथ ढीली व्यवस्थित होती हैं।

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Focused chapter-wise CBT practice builds the speed, mental stamina, and analytical discipline required to ace CUET, JEE Main, NEET UG, NDA, CA Foundation, and College Entrance Exams.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
