Heat resistant plants: How do plants protect themselves from the heat?
With the higher temperatures and longer heat waves, amateur gardeners should improve their hot weather gardening skills. How to protect your garden from heat , we have already explained. But have you ever wondered if and how plants protect themselves from the heat? We protect it from the sun by sweating and releasing fluids through our skin. We then make up for this fluid by drinking it. Well, plants do much the same as we do – when it gets quite hot, they take water from the soil, then transport it into the leaves and then release it on the underside of the leaves through smaller openings.
However, due to lower water saturation, the plants are constantly releasing water into the air and have to stop photosynthesizing. Or to put it more simply – during a heat wave, they live on the back burner. In other plant species, such as the sand strawflower, the light-colored hair felt reflects solar radiation and ensures that the plant does not dry out. Thick leaves with a wax layer also reduce water loss and protect against heat.
