Flowering plants attribute to keep the surrounding pleasant and wet compared to non flowering plants. It was found by expert in this field.In the Amazon basin, replacing non flowering plant with varieties would result in an 80 percent rapid decrease in the area which is always covered by a wet rainforest.
Here is a lead author, Kevin Boyce, Associate Professor in Geophysical Sciences at the University of Chicago said, “The vein density of leaves within the flowering plants is much, much higher than all other plants,”
“That actually matters physiologically for both taking in carbon dioxide from the atmosphere for photosynthesis and also the loss of water, which is transpiration. The two necessarily go together. You can’t take in CO2 without losing water,” he added.
This suggests that flowering plants are important in taking water from the soil, get back into the sky, and returning in the form of rain to the Earth .Thus, flowering plants, called angiosperms, evolved around 120 million years ago, during the Cretaceous Period, and took another 20 million years to become prevalent.
“They’re basically everywhere and everything, unless you’re talking about high altitudes and very high latitudes,” Boyce said.
Boyce and Lee are working toward contributing the climatic impact of flowering plant evolution in the prehistoric world. This contribution showed the significant of flowering plants into water recycling. Rain falls, plants absorb rain water and send it out through leaves and goes back into the sky. These Flowering plants play important role in fostering and perpetuating their own diversity.
With the replacing of flowering plants with non flowering plants in eastern North America decreased rainfall up to 40 percent. This same replacement was done in Amazon basin and found that the onset of the monsoon was delayed from Oct. 26 to Jan. 10.
