The majority plants daytime carry on the photosynthesis, the absorption carbon dioxide, the release oxygen; Carries on the respiration at night, the absorption oxygen, the release carbon dioxide.But somewhat plants the laws of nature to be opposite, if the cactus is the daytime releases the carbo...

In either case, though, the result would have been fairly the same: Dust would have blocked out the sun, hurting life-giving processes like photosynthesis(光合作用).Mystery 3: Will we ever be able to predict earthquakes?We still haven't been able to come up with a way to exactly ...
During winter, there is not enough light or water for photosynthesis. The trees will rest, and live off the food they stored during summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves. As the bright green fades away, we begin to see...
This is actually something researchers want to know about maize, when did people first start to plant it as a crop. So what we’ve been able to do is identify ancient sites of maize agriculture, take samples from different soil layers, and study the phytoliths from each layer. The deeper...
Note that fall foliage isn’t due to current weather conditions. This is a common misconception. Leaves change color because of the amount of daylight and photosynthesis.Learn more about autumn leaves. Fall EquinoxFAQs Q: Are Day and Night Perfectly Equal on the Equinox?
We cannot get round photosynthesis. We cannot say I am not going to give a damn about phytoplankton. All these tiny mechanisms provide the preconditions of our planetary life. To say we do not care is to say in the most literal sense that "we choose death." — Barbara Ward, Baroness ...
