**Question:**
Which is a difference between proteins and DNA?

**Options:**
- Proteins contain carbon atoms, DNA does not
- DNA is found in the cell membrane, proteins are only in the cytoplasm
- DNA is mostly contained in the nucleus, proteins are found in nucleus and cytoplasm
- Proteins store information, DNA catalyzes reactions

**Explanation:**
This question asks for a distinguishing feature between proteins and DNA. Consider the properties and locations of biological molecules to identify the correct answer.

During the photosynthesis laboratory, we used the leaf disk method for measuring the photosynthetic rate. After 20 minutes of receiving light, leaf disks floated again. The phenomenon occurred because the mesophile (internal layer of leaves):

- ○ received water from the solution
- ○ trapped water
- ○ received a hydrogen ion
- ○ produced oxygen
