The first 3 of 30 questions. Unlock the series for the rest, each with a solution.
Q1. Which one of the following is NOT a false fruit?
निम्नलिखित में से कौन-सा कूट फल (मिथ्या फल) नहीं है?
- A. Cashew nut / काजू
- B. Apple / सेब
- C. Pear / नाशपाती
- D. Tomato / टमाटर
Solution
A false fruit develops from a floral part other than the ovary (e.g. the thalamus in apple and pear, or the peduncle/receptacle in cashew). Tomato is a true fruit because it develops only from the ovary.
कूट फल अंडाशय के अतिरिक्त किसी अन्य पुष्पीय भाग से विकसित होता है (जैसे सेब और नाशपाती में पुष्पासन, या काजू में पुष्पवृंत/पुष्पासन)। टमाटर एक सत्य फल है क्योंकि यह केवल अंडाशय से विकसित होता है।
Q2. In which of the following plants are the tendrils modifications of the stem (axillary branches)?
निम्नलिखित में से किन पादपों में प्रतान (टेंड्रिल) तने (कक्षस्थ शाखाओं) के रूपांतरण होते हैं?
- A. Cucurbita / कुकुर्बिटा
- B. Pea / मटर
- C. Australian Acacia / ऑस्ट्रेलियाई अकेसिया
- D. Nepenthes / नेपेंथीस
Solution
In Cucurbita (gourds/cucumber) the tendrils are modified axillary stem branches. In pea the tendrils are modified leaflets, Nepenthes has a modified leaf lamina (pitcher), and Australian Acacia has a modified petiole (phyllode).
कुकुर्बिटा (लौकी/खीरा) में प्रतान रूपांतरित कक्षस्थ तने की शाखाएँ होते हैं। मटर में प्रतान रूपांतरित पर्णक होते हैं, नेपेंथीस में रूपांतरित पर्णदल (घटपर्णी) होता है, और ऑस्ट्रेलियाई अकेसिया में रूपांतरित पर्णवृंत (फिलोड) होता है।
Q3. The wall thickenings of collenchyma are chiefly due to the deposition of:
स्थूलकोणोतक की भित्ति का स्थूलन मुख्यतः किसके निक्षेपण के कारण होता है:
- A. Cutin / क्यूटिन
- B. Lignin / लिग्निन
- C. Suberin / सुबेरिन
- D. Cellulose, hemicellulose and pectin / सेलुलोस, हेमीसेलुलोस और पेक्टिन
Solution
Collenchyma walls are thickened by deposition of cellulose, hemicellulose and pectin and are not lignified; lignin thickens sclerenchyma, suberin forms cork, and cutin forms the cuticle.
स्थूलकोणोतक की भित्तियाँ सेलुलोस, हेमीसेलुलोस और पेक्टिन के निक्षेपण द्वारा स्थूलित होती हैं और लिग्निनयुक्त नहीं होतीं; लिग्निन दृढ़ोतक को स्थूलित करता है, सुबेरिन काग बनाता है, और क्यूटिन उपत्वचा बनाता है।
