Fill in the following blanks with suitable words:
In plant cells, oxygen is used to break down ……. Into carbon dioxide and water, and release …………

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Process**: In plant cells, respiration is a process where oxygen is used to break down substances to release energy.

2. **Identifying the Substance**: The primary substance that is broken down during respiration in plants is glucose. Glucose is a type of carbohydrate that plants produce during photosynthesis.

3. **Chemical Reaction**: When glucose is broken down in the presence of oxygen, it results in the production of carbon dioxide and water. This is a crucial part of the respiration process.

4. **Energy Release**: The breakdown of glucose not only produces carbon dioxide and water but also releases energy, which is essential for the plant's growth and functioning.

5. **Filling in the Blanks**: Based on the understanding of the process:
- The first blank is filled with "glucose".
- The second blank is filled with "energy".

**Final Statement**: In plant cells, oxygen is used to break down **glucose** into carbon dioxide and water, and release **energy**.
