Most angiosperms have alternate phyllotaxy. What allows each leaf to get the maximum exposure to light and reduces shading of lower leaves?

Question

Quizplus · Accepted Answer

Alternate phyllotaxy with a leaf angle of 137.5° allows each leaf to receive maximum exposure to light while minimizing shading of lower leaves. This arrangement ensures that leaves are spaced out to maximize exposure to sunlight for efficient photosynthesis. Leaf area index is not necessarily related to phyllotaxy, and self-pruning and one leaf per node are not typical characteristics of alternate phyllotaxy.
