The upper leaves of sugar beets grow vertically and the leaf clusters are funnel-shaped. The foliar space preparation structure formed by this growth method is extremely effective at absorbing light and improving the photosynthetic efficiency of plants and groups. The leaves of plantain are round The angle of the leaves is 137.5 degrees, which is the chord angle of the round golden section. The leaves grow at this angle to make full use of the light. As the trunk grows, the leaves rise in a logarithmic spiral, and each leaf Neither will obscure the underlying leaves. The text is intended to explain:. ['Light absorption is a key factor affecting plant growth.', 'Leaf structure that coincides with mathematical rules is beneficial to plant growth.', 'Different growth environments cause differences in plant leaf growth.', 'The absorption of light affects the growth angle of the leaves.']
