The sunlight provides energy for the plants to grow. <span>Since it is a closed system, no water would be lost, so it is not necessary to add extra water. </span>
B. cellular respiration, Hope this helps!
In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis. Critical in this process is the stoma. Stomata (multiple stoma) are located on the outermost cellular layer of leaves, stems, and other plant parts. An open stoma facilitates the process of photosynthesis in three ways. First, it allows light to enter the intercellular matter and trigger the process. Second, it allows for the uptake of carbon dioxide, a key chemical in producing plant energy. Third, it allows for oxygen to be expelled into the outside environment, a byproduct of photosynthesis that is no longer needed by the cell.
Scientific method includes some steps that are necessary for conducting the successful experiment.
1. Make an observation
You observe the growth of the plant under the influence of light (phototropic effect) and you notice that some plants successfully grow under artificial light. You want to compare that growth with growth under the sunlight.
2. Ask a question
How does the light influence plant growth?
Are the wavelengths of the light important?
Is natural light source (sun) better for plant growth...
3. Form a hypothesis - it is a testable potential answer to the question
For example: Sunlight induces higher phototropic reaction.
4. Make a prediction
Sunlight is richer in red and blue hues which are both extremely important to plant growth.
5. Test the prediction
Design an experiment by putting one pot with beans outside on sunlight and other under the light bulb. Other conditions such as water must be the same. Monitor their growth for about 2 weeks and measure the results.
6. Analyze the data and make a conclusion.
