A bottle containing germinating seeds is connected to a tube having lime water. After sometime, the lime water turns

Options

A. Red
B. Brown
C. Green
D. White

Answer

To solve the question, we need to understand the process occurring in the bottle with germinating seeds and how it affects the lime water.

### Step-by-Step Solution:

1. **Understanding Germinating Seeds**: Germinating seeds undergo cellular respiration to generate energy for growth and development. This process involves the breakdown of stored nutrients in the seeds.

2. **Respiration Process**: During cellular respiration, seeds consume oxygen and produce carbon dioxide (CO2) as a byproduct. This is an essential process for the seeds to grow and mature.

3. **Connection to Lime Water**: The bottle containing the germinating seeds is connected to a tube that leads to lime water. Lime water is a solution of calcium hydroxide (Ca(OH)2) in water.

4. **Reaction with Carbon Dioxide**: When carbon dioxide is bubbled through lime water, it reacts with calcium hydroxide to form calcium carbonate (CaCO3), which is insoluble in water. This reaction causes the lime water to turn milky.

5. **Conclusion**: Since the germinating seeds release carbon dioxide during respiration, the lime water will turn milky white due to the formation of calcium carbonate.

6. **Final Answer**: Therefore, after some time, the lime water turns **white**.
