Is transpiration part of the gas exchange system in plants , the water exchange system in plants or both

Transpiration is part of the water exchange system. The gas exchange system occurs through the stomata but is not part of transpiration. Transpiration occurs when plants absorb water through their roots and then give off water via the pores in their leaves. The process of transpiration cools plants down when they get too hot. Plants "sweat" in the same way that animals sweat to cool down. The water that is passed through the stomata evaporates and cools the plant down.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.
