Differences observed in the cups with and without baking soda as carbon source in photosynthesis floating leaf experiment
Differences observed in the cup with baking soda as carbon source
- The leaf in the cup with baking soda as carbon source will float to the surface of the water.
- The leaf will turn green due to the presence of chlorophyll in the leaf, which is essential for photosynthesis to occur.
- The baking soda will provide carbon dioxide which is necessary for the process of photosynthesis.
- Oxygen bubbles will be produced as a result of photosynthesis.
Differences observed in the cup without baking soda as carbon source
- The leaf in the cup without baking soda as carbon source will not float to the surface of the water.
- The leaf may not turn green due to the absence of chlorophyll, which is necessary for photosynthesis to occur.
- No oxygen bubbles will be produced as a result of photosynthesis.
Explanation
The photosynthesis floating leaf experiment involves placing a leaf in a cup of water and observing the process of photosynthesis. Photosynthesis is the process by which plants make their food using sunlight, water, and carbon dioxide. In this experiment, the baking soda acts as the source of carbon dioxide. Carbon dioxide is essential for photosynthesis to occur as it is used by the plant to make glucose.
In the cup with baking soda as carbon source, the leaf will float to the surface of the water, turn green due to the presence of chlorophyll and produce oxygen bubbles as a result of photosynthesis. However, in the cup without baking soda as carbon source, the leaf will not float, may not turn green due to the absence of chlorophyll and no oxygen bubbles will be produced.
In conclusion, the presence of baking soda as a carbon source is necessary for the process of photosynthesis to occur in the floating leaf experiment.
