What is DEDIFFERENTIATION and REDIFFERENTIATION in plant tissue culture?

पादप ऊतक संवर्धन में 'वि-विभेदन' (Dedifferentiation) तथा 'पुनर्विभेदन' (Redifferentiation) क्या है?

Dedifferentiation: Mature living differentiated cells regain power of cell division to form meristem/CALLUS (e.g. Interfascicular cambium, Cork cambium); Redifferentiation: Dedifferentiated cells divide and lose division power to mature into specialized secondary tissuesवि-विभेदन: विभेदित कोशिकाओं द्वारा पुनः विभाजन क्षमता प्राप्त करना (कैम्बियम/कैलस); पुनर्विभेदन: वि-विभेदित कोशिकाओं द्वारा विशिष्ट ऊतक बनाना

Redifferentiation occurs only in embryonic seedsपुनर्विभेदन केवल भ्रूणीय बीजों में होता है

Dedifferentiation is permanent cell deathडिडिफ़रेंशिएशन स्थायी कोशिका मृत्यु है

Both mean normal mitosisदोनों का मतलब सामान्य माइटोसिस है

Correct Answer: Option A

Explanation:

Developmental plasticity: (1) Differentiation: Primary meristematic cells mature and lose division power (e.g. tracheary elements); (2) DEDIFFERENTIATION: Living differentiated cells regain the capacity of cell division under certain conditions (e.g. formation of interfascicular cambium and cork cambium from fully differentiated parenchyma cells, or Callus formation in culture); (3) REDIFFERENTIATION: Cells produced by dedifferentiated meristems once again lose division power and mature to perform specific functions (e.g. secondary xylem, secondary phloem, cork).

वि-विभेदन व पुनर्विभेदन की अवधारणा।

What is the RICHMOND-LANG EFFECT demonstrated by Cytokinins?

साइटोकाइनिन द्वारा प्रदर्शित 'रिचमंड-लैंग प्रभाव' (Richmond-Lang Effect) क्या है?

DELAY OF LEAF SENESCENCE (Aging) by promoting nutrient mobilization and preserving chlorophyll in detached leavesपत्तियों की जीर्णता (बुढ़ापा) को टालना तथा क्लोरोफिल को नष्ट होने से बचाना

Instant seed germination in darkअंधेरे में तुरंत बीज का अंकुरण

Accelerated leaf shedding in autumnशरद ऋतु में पत्तियों का तेजी से झड़ना

Correct Answer: Option A

Explanation:

Cytokinins help overcome apical dominance, promote chloroplast development, and significantly DELAY LEAF SENESCENCE (aging of leaves) by promoting nutrient mobilization and protein retention, a biological phenomenon known as the RICHMOND-LANG EFFECT.

साइटोकाइनिन जीर्णता को रोककर पत्तियों को हरा बनाए रखता है।

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.
