In an experiment, plants were grown under colored filters that allowed equal amounts of light of different colors to strike different plants. Under which filter do you think plants grew the slowest? Why?

Plants cannot use the green spectrum. I do not know what light you used.

In order to determine under which filter plants grew the slowest, we need to consider the role of different colors of light in plant growth.

Plants primarily use red and blue light for photosynthesis, which is the process through which they convert light energy into chemical energy to fuel their growth. Green light, on the other hand, is not efficiently absorbed by plants and is typically reflected, which is why most plants appear green.

Based on this information, we can deduce that plants would grow the slowest under a green filter. This is because green light would not provide the necessary energy for plants to carry out photosynthesis effectively. Therefore, when exposed to green light, plants would not be able to generate enough energy to support their growth, resulting in slower growth rates compared to plants exposed to red or blue light.

To determine under which filter plants grew the slowest, you would need to understand the requirements for plant growth and the effects of different colors of light on plants. Here's how you can approach finding the answer:

1. Research plant growth requirements: Begin by studying the basic requirements for plant growth, which include sufficient light, water, nutrients, and appropriate temperature. Light is crucial for photosynthesis, the process by which plants convert light energy into chemical energy.

2. Investigate the effects of different light colors: Look into the effects of various colors of light on plant growth. Different wavelengths of light have different effects on plant growth and development. For example, red and blue light are most commonly used by plants in photosynthesis, while green light is less effective.

3. Understand plant pigments: Learn about the different pigments present in plants, such as chlorophyll. Chlorophyll is responsible for absorbing light energy needed for photosynthesis. Different pigments have varying absorption spectra, meaning they absorb specific colors of light more effectively.

4. Analyze the given information: Consider the filters used in the experiment, which allowed equal amounts of different colors of light to reach each plant. If all the filters are equally efficient in transmitting light, the plants grown under the filter that transmits wavelengths of light that plants utilize least effectively would be expected to grow slower.

5. Make an informed prediction: Based on your research, make a prediction about the filter under which plants likely grew the slowest. For example, if green light is less effective for photosynthesis compared to red and blue light, and the filter used transmits green light, you could hypothesize that plants grown under that filter grew the slowest.

Remember, the actual answer may vary based on the specific experiment and the characteristics of the filters used. It is important to thoroughly research plant physiology and light effects on photosynthesis to make an accurate prediction.
