A few healthy gram seeds are placed in each of the three pots X, Y and Z containing same type of soil. The soil in pot X is mixed with some green leaves. The soil in pot Y is mixed with old cow dung while soil of pot Z is mixed with urea. Pots are watered regularly and given proper environment for plant-growth. Which of the following will be observed after 10 days?
- a)Lot of growth in Z with replenishment of all the nutrients.

A few healthy gram seeds are placed in each of the three pots X, Y and...
Explanation:
Introduction:
In this experiment, three pots (X, Y, and Z) containing the same type of soil are used. The pots are then mixed with different substances: green leaves, old cow dung, and urea. The pots are watered regularly and provided with a suitable environment for plant growth. After 10 days, the observation is made to determine which pot shows the most growth.
Explanation:
The correct answer is option 'C' - Lot of growth in Y with replenishment of the nutrients.
Reasoning:
1. Green leaves in pot X:
- Green leaves are a source of organic matter and contain a variety of nutrients.
- When mixed with soil, the organic matter in the green leaves decomposes and releases nutrients, which are then available for plant uptake.
- This provides a good source of nutrients for the plants in pot X, resulting in growth.
2. Old cow dung in pot Y:
- Cow dung is a well-known organic fertilizer and is rich in nutrients such as nitrogen, phosphorus, and potassium.
- When mixed with soil, the nutrients present in the cow dung are released slowly over time, providing a sustained supply of nutrients for plant growth.
- This continuous supply of nutrients promotes the growth of plants in pot Y.
3. Urea in pot Z:
- Urea is a synthetic fertilizer that contains a high concentration of nitrogen.
- When mixed with soil, urea quickly dissolves in water and releases nitrogen, which is readily available for plant uptake.
- Nitrogen is an essential nutrient for plant growth and is required in large quantities.
- The availability of nitrogen from urea promotes the growth of plants in pot Z.
Conclusion:
After 10 days, the observation will show a lot of growth in pot Y, which is mixed with old cow dung. This is because the cow dung provides a sustained supply of nutrients for plant growth. Pot X, mixed with green leaves, will also show growth due to the release of nutrients from the organic matter. Pot Z, mixed with urea, will show some growth as well, but not as much as pot Y, as urea provides a quick but short-term supply of nitrogen. Therefore, option 'C' - Lot of growth in Y with replenishment of the nutrients - is the correct answer.

Therefore, option 'C' - Lot of growth in Y with replenishment of the nutrients - is the correct answer.
