Free Sneak Peek

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.

The opening and closing of microscopic stomatal pores on plant leaves is strictly regulated by the turgor pressure changes in:

पौधों की पत्तियों पर रंध्रों (Stomata) के खुलने और बंद होने की प्रक्रिया मुख्य रूप से किन कोशिकाओं के स्फीति दाब (Turgor pressure) में परिवर्तन द्वारा नियंत्रित होती है?

Xylem tracheids and vessels (जाइलम वाहिकाएं)

Specialized kidney-shaped Guard Cells (वृक्काकार द्वार कोशिकाएं)

Dead cork cells of the outer bark (कार्क कोशिकाएं)

Pollen grains situated in anthers (परागकण)

Correct Answer: Option B

Explanation:

Stomatal pores are flanked by two specialized kidney-shaped guard cells. When water flows into guard cells, they swell, curve outward, and open the stoma. When they lose water, they become flaccid and the pore closes.

रंध्र दो वृक्काकार 'द्वार कोशिकाओं' (Guard cells) से घिरे होते हैं। जब द्वार कोशिकाओं में जल प्रवेश करता है तो वे फूलकर मुड़ जाती हैं और रंध्र खुल जाता है। जल बाहर निकलने पर वे ढीली पड़ जाती हैं और रंध्र बंद हो जाता है।

Study the graph showing photosynthesis rate across different colors of visible light:

Why does chlorophyll in green leaves exhibit the lowest rate of photosynthesis under green light?

दृश्य प्रकाश के विभिन्न रंगों में प्रकाश संश्लेषण की दर दर्शाने वाले आरेख का अध्ययन कीजिए:

हरी पत्तियों में उपस्थित क्लोरोफिल हरे प्रकाश में प्रकाश संश्लेषण की न्यूनतम दर क्यों प्रदर्शित करता है?

Green light destroys all water molecules inside chloroplasts instantlyहरा प्रकाश क्लोरोप्लास्ट के सभी जल अणुओं को तुरंत नष्ट कर देता है

Green light cools the leaf down to sub-zero freezing temperaturesहरा प्रकाश पत्ती को शून्य से नीचे जमा देता है

Green light converts starch into poisonous hydrogen gasहरा प्रकाश स्टार्च को जहरीली हाइड्रोजन गैस में बदल देता है

Chlorophyll pigments reflect green light rather than absorbing it; blue and red wavelengths are absorbed most efficientlyक्लोरोफिल वर्णक हरे प्रकाश को अवशोषित करने के बजाय परावर्तित कर देता है, जबकि नीले व लाल प्रकाश को सबसे अधिक अवशोषित करता है

Correct Answer: Option D

Explanation:

Chlorophyll pigments primarily absorb blue and red wavelengths of the solar spectrum to drive photosynthesis. Green light is largely reflected (giving leaves their characteristic green color), resulting in minimum photosynthetic activity.

क्लोरोफिल मुख्यतः नीले और लाल रंग के प्रकाश का अवशोषण करता है। यह हरे प्रकाश को अवशोषित नहीं करता बल्कि उसे परावर्तित कर देता है (इसीलिए पत्तियां हरी दिखती हैं), जिससे हरे प्रकाश में प्रकाश संश्लेषण लगभग नगण्य होता है।

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

Early practice in middle school builds the mental muscle, speed, and analytical discipline required to ace NTSE, Olympiads, JNVST, Sainik School, and Future Competitive 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.
