Mar 10, 2020 · For plants, sunlight can be a double-edged sword. They need it to drive photosynthesis, the process that allows them to store solar energy as sugar molecules, but too much sun can dehydrate and damage their leaves. A primary strategy that plants use to protect themselves from this kind of photodamage is to dissipate the extra light as heat.
Sep 30, 2021 · Without enough sun, plants may start to lose their leaves, and lack of sunlight may also cause plants to conserve energy by not producing flowers. On the other hand, too much sunlight may cause bleaching of leaves. Plants do have a mechanism called photoprotection to shield themselves from too much sun, but this only works to a certain extent.
Jan 21, 2005 · Plants have a defense mechanism to protect them against excess sunlight. Sun screen. The carotenoid zeaxanthin (as seen under a microscope) is key to protecting plants from excess sunlight. Plants are supposed to crave sunlight, but too much sunlight can create potentially deadly free radicals. Now researchers have identified a mechanism plants ...

Mar 9, 2023 · Global light pollution has increased by at least 49% over 25 years. While its impacts are still being studied and vary widely across species, scientists do know light pollution is affecting how ...
Apr 22, 2021 · 22 April 2021. That a switching protein plays a role in protecting a plant from too much sunlight was already known, but how exactly was not yet understood. The research group of Anjali Pandit has now discovered that this protein changes shape when there is too much sunlight. The results have been published in Nature Communications.
