Which of the following represents
Which of the following represents a similarity between chloroplast and Mitochondria?
निम्नलिखित में से कौन – सा हरितलवक और माइटोकॉन्ड्रिया के बीच समानता को निरुपित करता हैं?
Detailed Solution & Logic
Both posses their own DNA and 70S Ribosome./ दोनों में अपना स्वयं का DNA और 70S राइबोसोम होता हैं।
🌿 Explanation
Chloroplasts and mitochondria are similar because both are semi-autonomous organelles. They contain their own DNA and 70S ribosomes, which allow them to synthesize some of their own proteins and replicate independently inside the cell.
Why other options are incorrect:
Both perform respiration – Only mitochondria perform cellular respiration.
Both have chlorophyll – Chlorophyll is present only in chloroplasts.
Both perform photosynthesis – Photosynthesis occurs only in chloroplasts.
Extra Facts:
Both organelles have a double membrane structure.
They are believed to have originated from bacteria according to the endosymbiotic theory.
Mitochondria produce ATP (energy), while chloroplasts prepare food.
🌿 व्याख्या
हरितलवक (Chloroplast) और माइटोकॉन्ड्रिया (Mitochondria) में समानता यह है कि दोनों अर्ध-स्वायत्त (semi-autonomous) कोशिकांग हैं। इनमें अपना स्वयं का DNA और 70S राइबोसोम पाया जाता है, जिससे ये कुछ प्रोटीन स्वयं बना सकते हैं तथा कोशिका के अंदर विभाजित हो सकते हैं।
अन्य विकल्प क्यों गलत हैं:
दोनों श्वसन करते हैं – श्वसन केवल माइटोकॉन्ड्रिया में होता है।
दोनों में क्लोरोफिल होता है – क्लोरोफिल केवल हरितलवक में पाया जाता है।
दोनों प्रकाश संश्लेषण करते हैं – प्रकाश संश्लेषण केवल हरितलवक में होता है।
अतिरिक्त तथ्य:
दोनों में दोहरी झिल्ली (double membrane) होती है।
एंडोसिम्बायोटिक सिद्धांत के अनुसार इनकी उत्पत्ति प्राचीन बैक्टीरिया से मानी जाती है।
माइटोकॉन्ड्रिया ऊर्जा (ATP) बनाते हैं, जबकि हरितलवक भोजन का निर्माण करते हैं।
