Which is one benefit and one drawback of transpiration?

Correct answer: It helps pull water upward but can also cause excess water loss

Transpiration is the loss of water vapour from the aerial parts of a plant, mainly through stomata. Evaporation creates transpiration pull, which helps lift water and dissolved minerals through the xylem. However, rapid or excessive transpiration may remove more water than the plant can absorb, causing wilting. Thus option A correctly gives both a benefit and a drawback; the other options mix unrelated digestive, urinary, or respiratory functions.
