Practice question
Question
In spiral phyllotaxis, leaves are initiated sequentially on the meristem with two successive primordia being separated by golden angle. If a plant follows right-handed spiral phyllotaxis when looked down the meristem, then the angle between two successive leaves would be degrees (with correct sign, round off to one decimal place). (NAT)
Explanation
This outcome reflects enzyme kinetics, where substrate binding and catalytic efficiency determine reaction rates. Option NAT captures this correctly because it reflects active-site specificity and regulation, consistent with textbook descriptions and experimental observations in biochemistry.
