A botanist has been examining three plants, measuring the amount of acid in their cells, and examining sections of their leaves under the microscope. Numbers in the table are in relative units.

Part A:

Identify the kind of photosynthesis being done by each plant. Explain how enzymes contribute to this data.

Part B:

Decipher the origin of each plant if one is from the Mojave Desert, one is from a sand dune in Florida, and one is from Minnesota, and explain how you deciphered this.

| Plant | Acid, day | Acid, night | Has wreath anatomy? | FADH₂ | Ethanol |
|-------|-----------|------------|---------------------|-------|---------|
| A     | 20        | 250        | No                  | 0     | 50      |
| B     | 10        | 10         | No                  | 100   | 1       |
| C     | 200       | 10         | Yes                 | 100   | 1       |

### Explanation:

- **Plant A:** Has a high acid level at night (250) compared to the day (20). It does not exhibit wreath anatomy and produces 0 FADH₂ with an ethanol level of 50.
- **Plant B:** Maintains equal acid levels of 10 during both day and night. It lacks wreath anatomy but produces a significant amount of FADH₂ (100) and has an ethanol level of 1.
- **Plant C:** Shows a reverse pattern with a high acid level during the day (200) and significantly lower at night (10). It has wreath anatomy, produces 100 FADH₂, and has an ethanol level of 1.
