ConclusionSunlight influence the growth of red beans

for their survival, because the sunlight is the source of energy that is used for the process photosynthesis which influence cell division in growth.

And the growth of red beans that adequate sunlight is slower than the growth of red beans that lack of sunlight. It happens because red beans plants which are not exposed by sunlight can maximize the hormon auxin for the elongation of plant cells, which causes plants to grow faster with pale condition, thin and the leaves are not developing or called ETIOLASI.Meanwhile, the growth of red beans are exposed to sunlight get inhibitory effect of auxin by the sunlight, it causing plants to grow slowly, with the condition is relatively short, well-developed and has green leaves.

Thanks for your attention !Any Question ??
