The C4 cycle (Hatch and Slack Pathway) is a photosynthetic process in some plants where CO₂ is initially fixed into a four-carbon compound. This adaptation minimizes photorespiration and enhances efficiency by concentrating CO₂ around RuBisCO, enabling better performance under high light intensity, high temperatures, and low CO₂ conditions. This is […]
Photorespiration is a process in plants where the enzyme RuBisCO oxygenates RuBP, leading to the release of CO₂ instead of its fixation. This occurs when oxygen levels are high, reducing photosynthetic efficiency and wasting energy, particularly under stress conditions like high temperatures. This is an MCQ on Photorespiration (C2 Cycle) […]
The Calvin cycle, also known as the C3 cycle, is a process in photosynthesis where carbon dioxide is converted into organic compounds like glucose. It consists of three phases: carbon fixation, reduction, and regeneration of ribulose-1,5-bisphosphate (RuBP). This is an MCQ on C3 Cycle of Photosynthesis. You may also like: […]
Photosynthesis is the biological process by which green plants, algae, and some bacteria convert sunlight, water, and carbon dioxide into glucose (a form of sugar) and oxygen. This process occurs in chloroplasts and is essential to produce energy-rich molecules, supporting the growth and sustenance of life on Earth. This is […]
MCQ on Phloem Transport in Plants: Phloem transport in plants occurs through a process called translocation. Sugars, mainly sucrose, produced in photosynthetic source tissues are actively loaded into the phloem. This creates a pressure gradient, causing sugars to flow through sieve tubes to sink tissues, where they are utilized or […]
