Q1. The five-kingdom system of classification was proposed by R.H. Whittaker. In which year was this system published?
वर्गीकरण की पाँच-जगत (five-kingdom) प्रणाली R.H. Whittaker द्वारा प्रस्तावित की गई थी। यह प्रणाली किस वर्ष में प्रकाशित हुई थी?
- A. 1965
- B. 1969
- C. 1977
- D. 1959
Solution
R.H. Whittaker proposed the five-kingdom classification (Monera, Protista, Fungi, Plantae, Animalia) in 1969, based on criteria such as cell structure, body organisation, mode of nutrition, reproduction and phylogenetic relationships.
R.H. Whittaker ने पाँच-जगत वर्गीकरण (Monera, Protista, Fungi, Plantae, Animalia) को 1969 में प्रस्तावित किया, जो कोशिका संरचना, शरीर संगठन, पोषण की विधि, जनन तथा जातिवृत्तीय (phylogenetic) संबंधों जैसे मानदंडों पर आधारित था।
Q2. The chrysophytes of Kingdom Protista include which of the following two groups of organisms?
जगत प्रोटिस्टा के क्राइसोफाइट्स में जीवों के निम्नलिखित में से कौन-से दो समूह सम्मिलित हैं?
- A. Dinoflagellates and golden algae (desmids) / डाइनोफ्लैजेलेट और स्वर्णिम शैवाल (desmids)
- B. Euglenoids and slime moulds / यूग्लीनॉइड और अवपंक कवक (slime moulds)
- C. Diatoms and dinoflagellates / डायटम और डाइनोफ्लैजेलेट
- D. Diatoms and golden algae (desmids) / डायटम और स्वर्णिम शैवाल (desmids)
Solution
Chrysophytes comprise the diatoms and the golden algae (desmids), found in both freshwater and marine habitats.
क्राइसोफाइट्स में डायटम और स्वर्णिम शैवाल (desmids) सम्मिलित हैं, जो अलवणीय जल और समुद्री दोनों आवासों में पाए जाते हैं।
Q3. Which of the following correctly describes the structure of a mycoplasma?
निम्नलिखित में से कौन-सा माइकोप्लाज्मा की संरचना का सही वर्णन करता है?
- A. They have a cellulosic cell wall and are strictly aerobic / इनमें सेल्यूलोजी कोशिका भित्ति होती है और ये पूर्णतः वायवीय होती हैं
- B. They are eukaryotic cells lacking a nucleus / ये केंद्रक-रहित यूकैरियोटिक कोशिकाएँ होती हैं
- C. They completely lack a cell wall and are the smallest living cells known / इनमें कोशिका भित्ति पूर्णतः अनुपस्थित होती है और ये ज्ञात सबसे छोटी जीवित कोशिकाएँ हैं
- D. They possess a cell wall made of peptidoglycan and are the largest prokaryotes / इनमें पेप्टिडोग्लाइकन की बनी कोशिका भित्ति होती है और ये सबसे बड़े प्रोकैरियोट हैं
Solution
Mycoplasmas are the smallest living cells known, completely lack a cell wall, can survive without oxygen (many are anaerobic), and are pathogenic to plants and animals.
माइकोप्लाज्मा ज्ञात सबसे छोटी जीवित कोशिकाएँ हैं, इनमें कोशिका भित्ति पूर्णतः अनुपस्थित होती है, ये ऑक्सीजन के बिना जीवित रह सकती हैं (अनेक अवायवीय होती हैं), और ये पादपों तथा जंतुओं के लिए रोगजनक होती हैं।
