The plant withers and dies.
The plant withers and dies.

The plant grows and thrives.

Answer 1

The correct response is: The plant withers and dies.

Blocking the stomata with petroleum jelly prevents the plant from exchanging gases, particularly limiting its ability to transpire and take in carbon dioxide for photosynthesis. This would lead to stress and eventual decline in the plant's health, potentially causing it to wither and die.

Answer 3

In the photosynthesis reaction, the overall equation is:

\[ 6 , \text{CO}_2 + 6 , \text{H}_2\text{O} \rightarrow \text{C}6\text{H}{12}\text{O}_6 + 6 , \text{O}_2 \]

This shows that 6 molecules of carbon dioxide (CO₂) are used, which means 6 carbon atoms are involved in the reaction to produce one molecule of glucose (C₆H₁₂O₆).

Therefore, the correct response is: 6.
