MCQ on Microbes in Nitrogen Cycle: In the nitrogen cycle, essential for ecosystem health, microbes such as nitrogen-fixing bacteria, nitrifying bacteria, and denitrifying bacteria play pivotal roles. Nitrogen-fixers convert atmospheric nitrogen into ammonia, while others convert ammonia into nitrates and nitrites, shaping nutrient availability in ecosystems. Microbiology Notes | Microbiology […]
MCQ on Phospholipids: Phospholipids are essential components of cell membranes. They consist of a hydrophilic head and two hydrophobic tails. Arranged in a bilayer, they create a selectively permeable barrier, regulating the flow of molecules in and out of cells, vital for cellular integrity and function. Learn more: MCQ on […]
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 […]
MCQ on Significance of Hydrogen Bonds. Hydrogen bonds are crucial in various aspects of chemistry and biology. They stabilize protein and DNA structures, facilitating life’s essential processes. In water, they contribute to its unique properties. In molecules like DNA, they enable genetic information storage and transfer, underpinning life’s molecular machinery. […]
MCQ on Cell Signalling in Plants: In plants, cell signalling occurs through various mechanisms, including phytohormones like auxins, cytokinins, and gibberellins. These molecules regulate growth, development, and responses to environmental cues by binding to receptors and initiating intracellular pathways, ensuring coordinated physiological processes.
