Here, I have explained the conditions required and observations that were made when a sweet potato was made to grow in the above mentioned environment.

Sweet potatoes are dicotyledonous plants which belong to the morning glory family hence it requires more sun light and care like an Ivy plant.

Step 1:

Fill a jar with water to two third of its portion and submerge a sweet potato in it.

Step 2:

Two third of the Sweet potato must be kept submerged into the water. So use some tooth picks to impale the potato in order to hang the above stipulated portion of the potato to hang inside the water.

Step 3:

Keep the setup under direct sunlight.

Observation:

You can witness some branches of vines sprouting out from the Potato within two or three weeks. Cut off the vines when they grow too long in order to get a bushy like appearance.

Experiment: Growing a Sweet Potato in Water

Introduction:
Growing a sweet potato in water is a simple and fascinating experiment that allows you to observe the process of root growth and development. This experiment can be a great hands-on activity for understanding the basic principles of plant nutrition and the importance of water in plant growth.

Materials:
1. Sweet potato tuber
2. Glass jar or container
3. Toothpicks
4. Water

Procedure:
1. Select a healthy sweet potato tuber with several buds or "eyes" on its surface.
2. Fill a glass jar or container with enough water to submerge the bottom half of the sweet potato.
3. Insert toothpicks into the sides of the sweet potato, near the top, to hold it in place on the rim of the jar or container. The toothpicks should rest on the rim, suspending the sweet potato in the water.
4. Place the jar or container in a well-lit area, preferably near a window, to ensure the sweet potato receives sufficient sunlight.

Observations:
1. Within a few days, you may notice the development of small roots emerging from the buds or "eyes" of the sweet potato.
2. As time progresses, the roots will continue to grow longer and become more extensive, reaching deeper into the water.
3. After a week or two, you may observe the formation of small shoots or sprouts on the top of the sweet potato.
4. These shoots will gradually grow taller and develop leaves, indicating the beginning of above-ground growth.

Explanation - Nutrition in Plants:
Plants require certain nutrients for their growth and development. While soil is the primary source of these nutrients, water also plays a crucial role in transporting these substances to different parts of the plant. Through the experiment of growing a sweet potato in water, we can observe the following key points related to plant nutrition:

1. Water Absorption: The sweet potato tuber absorbs water through its roots, which are submerged in the water-filled jar. Water uptake is a vital process for plants as it enables the transportation of essential nutrients dissolved in water.

2. Root Growth: The growth of roots in the experiment demonstrates the importance of water in providing plants with a constant supply of nutrients. As the roots grow longer and more extensive, they can absorb water and minerals from the surrounding medium.

3. Shoot Development: The emergence of shoots and leaves on the sweet potato indicates that it is capable of obtaining the necessary nutrients solely from water. This shows that plants can adapt and utilize available resources to support their growth.

4. Photosynthesis: Once the sweet potato develops leaves, it can undergo photosynthesis, a process that converts sunlight into energy. This energy is utilized by the plant for various metabolic activities, including growth and reproduction.

In conclusion, growing a sweet potato in water provides a visual and practical understanding of plant nutrition. The experiment allows us to observe the importance of water as a medium for nutrient absorption and the subsequent growth of both roots and shoots. It also highlights the adaptability of plants in utilizing available resources for their survival and development.
