A scientist performs an experiment by placing petroleum jelly on under side of plant leaves. This blocks the leaves’ stomata. The plant continues to be watered and is located in a sunny spot. What will the scientist observe?
The plant withers and dies. By blocking the stomata with petroleum jelly, the plant cannot exchange gases (such as carbon dioxide and oxygen) with its surroundings. This will lead to a disruption in photosynthesis and the plant will not be able to produce enough food for survival. Over time, the plant will lose water through transpiration and eventually die.
