that’s an excellent example, unless you’re that cat that has glasses that turn into sunglasses when you walk outside, then it’s reversedYeah. I advise people to not take plants directly in or out without a period of in-between shade from the sun exposure. It's like people going from outdoors to a closet, or vice-versa, our light receptors wouldn't be able to adjust on a dime and we'd be temporarily blinded.
it makes sense that tropicals or arid plants given their natural environment and genetics -not exactly four seasons varying…do this
my understanding of most leaves is they are like solar panels that the plant can not just turn off, photosynthesis is a complex machine that demands from top to bottom, is no light switch
succulents are better adapted maybe in the way they can pause the machine to conserve water (CAM)
sometimes maybe, especially in an environment with less flux than a multitude of seasons, it’s just better to drop all the demands of resources exhausting solar panels than risk the potential stress throughout or in other more less adaptive areas of the plant.
because the biology of the plant is dialed to its natural habitat having no idea what winter or that you care (perhaps) exists, going into stasis, allocating resources to ideal and existing conditions makes a lot of sense -although, unlike their natural habitat inside the home is not the sun or perhaps humidity they expect..?
