A scientist performs an experiment by placing petroleum jelly on underside 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 scientist will observe that the plant's ability to transpire water through its stomata will be greatly reduced. This could lead to the plant becoming dehydrated and wilting, as it cannot release water vapor through its leaves. The plant may also show signs of stress, such as yellowing or browning of the leaves. Overall, the plant's growth and health may be negatively impacted by the blockage of its stomata.
