आर्द्र परिस्थितियों में एक स्वस्थ पत्ती के सिरे से तरल के स्राव की प्रक्रिया बिंदुस्राव कहलाती है, और यह प्रक्रिया किन विशिष्ट छिद्रों के माध्यम से होती है?
The condition required for transpiration (water to move through the plant from the soil to the air) is: [Note: soil water potential ($\psi_{soil}$), root water potential ($\psi_{root}$), leaf water potential ($\psi_{leaf}$), water potential in the atmosphere ($\psi_{atmosphere}$)]
वाष्पोत्सर्जन के लिए आवश्यक शर्त (जल का मृदा से पौधे के माध्यम से वायु में संचलन) क्या है? [नोट: मृदा जल विभव ($\psi_{soil}$), मूल जल विभव ($\psi_{root}$), पर्ण जल विभव ($\psi_{leaf}$), वायुमंडल का जल विभव ($\psi_{atmosphere}$)]
In trees at a height of 75 meters, the magnitude of gravitational component of water potential in leaves is:
75 मीटर की ऊंचाई वाले वृक्षों में, पत्तियों में जल विभव के गुरुत्वाकर्षण घटक का परिमाण कितना होता है?
In plant cells, the principal ion that is electrogenically pumped across membranes in plasma membrane and tonoplast is:
