Card 1Growth

What is growth in plants?

Answer

Growth is an irreversible permanent increase in size of an organ, its parts, or even a single cell. It is usually accompanied by anabolic and catabolic metabolic processes that use energy.

Card 2वृद्धि

पौधों में वृद्धि क्या है?

Answer

वृद्धि (Growth) किसी अंग, उसके भागों या एक अकेली कोशिका के आकार में अपरिवर्तनीय स्थायी वृद्धि है। यह आमतौर पर ऊर्जा का उपयोग करने वाली उपापचय और अपचय चयापचय प्रक्रियाओं के साथ होता है।

Card 3Growth

Why is plant growth called indeterminate?

Answer

Plants retain the capacity for unlimited growth throughout life because meristems keep dividing and adding new cells. This is called open form of growth.

Card 4वृद्धि

पौधे की वृद्धि को अनिश्चित क्यों कहा जाता है?

Answer

पौधे जीवन भर असीमित वृद्धि की क्षमता बनाए रखते हैं क्योंकि मेरिस्टेम विभाजित होते रहते हैं और नई कोशिकाओं को जोड़ते रहते हैं। इसे वृद्धि का खुला रूप कहा जाता है।

Card 5Meristem

What is a meristem?

Answer

A meristem is a region of actively dividing cells in a plant. Root apical meristem, shoot apical meristem, vascular cambium, and cork cambium are important examples.

Card 6मेरिस्टेम

मेरिस्टेम क्या होता है?

Answer

अवकल ऊतक (meristem) किसी पौधे में सक्रिय रूप से विभाजित हो रही कोशिकाओं का क्षेत्र होता है। मूल अग्रिक अवकल ऊतक, प्ररोह अग्रिक अवकल ऊतक, संवहनी कैम्बियम और कॉर्क कैम्बियम इसके महत्वपूर्ण उदाहरण हैं।

Card 7Phases of growth

What are the main phases of growth?

Answer

The three phases are meristematic, elongation, and maturation. Meristematic cells divide actively, elongation cells enlarge rapidly, and maturation cells reach full functional size and specialization.

Card 8विकास के चरण

विकास के मुख्य चरण क्या हैं?

Answer

तीन चरण हैं मेरिस्टेमेटिक, दीर्घीकरण और परिपक्वता। मेरिस्टेमेटिक कोशिकाएँ सक्रिय रूप से विभाजित होती हैं, दीर्घीकरण कोशिकाएँ तेजी से बढ़ती हैं और परिपक्वता कोशिकाएँ पूर्ण कार्यात्मक आकार और विशेषज्ञता
