The molecule that plants use to protect themselves from the dangers of getting too much sun during photosynthesis has now been revealed by a combination of ultrafast spectroscopy and plant genetics. Plants rely on sunlight to generate chemical energy via photosynthesis. It's been known for more than two decades that plants protect themselves from excess light, which can lead to oxidative damage to chlorophyll and other key photosynthetic pigments. But the biophysical mechanism of this protective process--known as feedback de-excitation--has remained mysterious. Chemist Graham R. Fleming, plant biologist Krishna K. Niyogi, and coworkers at Lawrence Berkeley National Laboratory and the University of California, Berkeley, have now shown that zeaxanthin, a carotenoid known to be produced by plants in response to bright sunlight, is responsible for the protective effect [Science,307, 433 (2005)]. Using femtosecond spectroscopic techniques and plant genetics, the team shows that exposing spinach leaves to intense light triggers the formation of zeaxanthin cation radicals. These cation radicals form when zeaxanthin binds to potentially dangerous photoexcited chlorophyll molecules. The zeaxanthin gives up an electron to the excited chlorophyll, yielding a chlorophyll anion radical and a zeaxanthin cation radical. These products subsequently undergo charge recombination, allowing the excited-state energy of chlorophyll to be safely dissipated as heat. The study is "a major advance in understanding how feedback de-excitation works at the molecular level," comments Robert E. Blankenship of Arizona State University. It "points the way to studies in which this mechanism might be manipulated for practical uses," he adds, such as protecting artificial photosynthetic systems used for solar energy generation from light-induced damage. poopy poo no!!

Plants can die from too little sunlight because they turn the sunlight into sugars the plant needs to survive. Too much sunlight can lead to an overdose in sugar levels in the plant and it will dry out, but it somewhat depends on the type of plant. Some like a lot of sunlight and little water, and some like a lot of water and little sunlight.

Yes, the plant will wilt and die due to necrosis, thanks to excessive sunlight

Most likely, because the heat causes the plants water supply to dry up/ causes the soil to dry up. it will die without water.

What happens to a plant if it gets too much sunlight and water?

Too much water and it will become root-bound ... the ground surrounding the plant will get moldy and then stricken the plant with diseases. Don't think a plant can get too much sunlight ... there's a difference between "sunlight" and "full sun". Sunlight is somewhat diffused.


What will happen to a plant that gets too much strong sunlight?

The plant will get sunburnt and can actually die


Why would a healthy plant outside just die?

The plant either had too much or too little water or sunlight.

In the bright sunlight what are the changes when a plant is put under a jar?

In the bright sunlight there are changes that occur when a plant is put under a jar. The plant would most likely shrivel from too much light.


Do different amounts of sunlight have an impact on plant growth?

Yes! Not enough will not allow the plant to grow (as they get energy from sunlight -- so without sunlight they cannot grow) and too much can burn some plants, causing them to die.


Does sunlight affects plans growth or does it needmore water?

Plants need sunlight and water to grow. It will die without water, and it will die without sunlight, it is just a matter of time. Different plants need different amounts of water and sunlight. What is not enough water for a rose may be too much water for a cactus. Likewise, what is not enough sunlight for a rose, may be too much sunlight for a rhododendrum. A plant with too little sunlight will not grow to it´s full height, and a plant with too little water will not grow to it´s full height either.


Can a plant decrease in size due to the amount of sunlight it receives?

Yes, too much sun and the plant will wilt, shrivel and get smaller. Too little sun and a plant may remain thin and weak.


13 How does the hours of sunlight affect the plant growth?

more sunlight= more growth however too much sun and or heat and or UV light will damage the plant and day length also has an effect on plant hormon cycle
