Question

what is transpiration? how the cactus plant in deserts adapted to reduce transpiration?​

Answer 1

Answer:

transpiration is the process in which excess water of the plants are evaporated through the leaf

as the cactus plant already lacks water so it has modified its leafs to thorn form to not transpirate excess water and use it for later

hence the cactus plant does not transpirate...

google answer:

The stomata of many cacti lie deep in the plants' tissues. This adaptation helps cacti reduce water loss by keeping the hot, dry wind from blowing directly across the stomata. ... Small leaves on desert plants also help reduce moisture loss during transpiration. Small leaves mean less evaporative surface per leaf.
