The step in photosynthesis that does not need light is:
**Carbon dioxide and hydrogen combine to make glucose.**
This process occurs during the Calvin cycle, which is the light-independent reaction of photosynthesis.

The correct response is:
**The plant withers and dies.**
Blocking the stomata with petroleum jelly prevents the plant from exchanging gases effectively (such as taking in carbon dioxide and releasing oxygen), which is essential for photosynthesis. Additionally, it may lead to water retention and prevent transpiration, both of which can negatively affect the plant's health and ultimately cause it to wither and die.

The correct response is:
**6**
In the photosynthesis reaction, specifically in the synthesis of one glucose molecule (C₆H₁₂O₆), six carbon atoms are used. This is represented in the overall equation of photosynthesis:
6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
Here, 6 molecules of carbon dioxide (CO₂) provide 6 carbon atoms for the glucose produced.
