The upper leaves of sugarbeet grow vertically and the leaf clusters are funnel-shaped. the configuration structure of foliar space formed by this growth mode is very powerful in the absorption of light and improves the photosynthetic efficiency of plants and populations.On the other hand, the leaves of plantain are whorled, and the angle between the leaves is 137.5 degrees, which is the chord angle of the golden section of the circle. The leaves grow according to this angle and can make full use of light.As the trunk grows taller, the leaves of the pear tree rise in a logarithmic spiral, and each leaf will not cover the leaves below.
The main content of this text is that different growth environments lead to differences in the growth of plant leaves.
