Introduction

Plants are essential to life on Earth. They provide oxygen, food, and shelter for all living organisms. However, we have always assumed that plants require sunlight and water to survive. In this science project, we aim to explore whether plants can grow without these two essential components.

Background Research

Photosynthesis is the process by which plants make food. It requires three things: water, carbon dioxide, and sunlight. The leaves of a plant absorb sunlight, and the energy from the sunlight turns the water and carbon dioxide into glucose and oxygen. This glucose is then used as food for the plant.

Without sunlight, plants cannot make food through photosynthesis. Without water, plants cannot transport nutrients or perform photosynthesis. Therefore, it seems impossible for plants to grow without sunlight and water.

Materials

3 pots

3 soil samples

3 bean seeds

Blindfold

Water spray bottle

Procedure

Plant one bean seed in each pot with soil.

Place one pot in a dark room and cover it with a blindfold to prevent any light from entering.

Place another pot in a well-lit area and water it regularly.

Place the third pot in a well-lit area but do not water it.

Observe and record the growth of each plant over the course of four weeks.

Results

The plant in the dark room did not grow as it did not receive any sunlight. The plant in the well-lit area without water died after three days, indicating that water is essential for plant growth. However, the plant in the well-lit area that was watered regularly did grow properly.

Conclusion

Based on the results of the experiment, it is clear that plants cannot grow without sunlight and water. These two components are essential for photosynthesis and transport of nutrients. Therefore, we should ensure that plants receive adequate sunlight and water to ensure their growth and survival.

Future Possibilities

It would be interesting to explore whether artificial light can substitute for sunlight in plant growth. Additionally, we can look at the effects of different types of light on plant growth. Finally, the effect of different types of water on plant growth can also be explored.
