How may a plant respond to severe heat stress? a. by reorienting leaves to increase evaporative cooling b. by creating air tubes for ventilation c. by producing heat-shock proteins, which may protect the plant's proteins from denaturing d. by increasing the proportion of unsaturated fatty acids in cell membranes, reducing their fluidity

Hi everyone. Let's look at the next problem. Which one is true with respect to heat shock proteins. And we have four um answers here. Choice D. Is all of these are true. So let's remember that we may have multiple correct answers here. So, as you might guess from the name um maybe a call from our content videos that heat shock proteins are produced in response to severe heat. Um as you might think is useful, they can withstand very high temperatures. Obviously you want that and something part of a severe hate response. And finally they help protect other proteins in the plant from being denatured. So when we look at our choices here, we've got choice A their plans to respond to severe heat stress. Plants response to severe heat stress. Yes, that is true choice B. They may protect the plants proteins from denature. Yes, they help protect other proteins from the neighboring. So that is true. And see there are special proteins that can withstand very high temperatures. That is true. So, we have three true answers here. So our correct answer is D all of these are true. And that is our answer for this problem. See you next time
