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
the plant goes into hibernation
the plant grows flowers and seeds
the plant grows and thrives

The scientist will observe that the plant withers and dies. Blocking the stomata, which are tiny openings on the underside of leaves responsible for gas exchange (such as carbon dioxide intake and oxygen release), prevents the plant from performing photosynthesis efficiently. As a result, the plant will not be able to produce enough energy and food to sustain itself, leading to its eventual death.
