MCQ on Gibberellins (Plant Hormone)
Gibberellins are plant hormones that act like growth spurts. They promote stem elongation, seed germination by breaking dormancy, and flowering in some plants. Imagine them […]

Ethylene, the “ripening hormone,” is a gas plants use to accelerate fruit ripening, leaf senescence, and flower petal abscission. It acts as a signal, triggering […]
Cytokinin are like cellular cheerleaders in plants. They promote cell division, shoot growth, and delay aging, keeping leaves green and buds ready to sprout into […]
Auxins are plant growth regulators that act like tiny conductors. They control cell elongation, root formation, and even tell plants which way to grow by […]
Abscisic acid (ABA) is a plant hormone nicknamed the “stress hormone.” It helps plants cope with drought, cold, and other threats by triggering responses like […]
Plant Hormone MCQ: Plant hormones, also known as phytohormones, are chemical substances that regulate various physiological processes in plants. They include auxins, gibberellins, cytokinins, ethylene, […]
A proton gradient is a difference in proton concentration across a membrane, created by the electron transport chain. ATP synthesis occurs when protons flow back […]
Chemiosmotic coupling is the mechanism by which ATP is synthesized in mitochondria and chloroplasts. It involves the movement of protons across a membrane, creating a […]
The Q cycle is a mechanism in the electron transport chain’s complex III (cytochrome bc1 complex) that transfers electrons from ubiquinol (QH2) to cytochrome c. […]
