Photosynthesis takes place faster in C. White light.
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar. The process takes place in the chloroplasts of plant cells. Chloroplasts contain chlorophyll, a green pigment that absorbs sunlight. When sunlight hits chlorophyll, it excites electrons. These excited electrons are used to power a series of reactions that convert carbon dioxide and water into oxygen and sugar.
The rate of photosynthesis depends on a number of factors, including the intensity of the light, the wavelength of the light, and the temperature. In general, photosynthesis takes place faster in brighter light and in light with a shorter wavelength, such as blue light. However, photosynthesis can also take place in red light, which has a longer wavelength. This is because chlorophyll absorbs red light as well as blue light.
White light is a mixture of all wavelengths of visible light. This means that white light contains all of the wavelengths of light that are necessary for photosynthesis. Therefore, photosynthesis takes place faster in white light than in any other type of light.
Here is a brief explanation of each option:
- A. Darkness. Photosynthesis does not take place in darkness because plants need sunlight to produce energy.
- B. Red light. Photosynthesis takes place faster in red light than in other colors of light, but it still takes place faster in white light.
- C. White light. White light is a mixture of all wavelengths of visible light, so it contains all of the wavelengths of light that are necessary for photosynthesis. Therefore, photosynthesis takes place faster in white light than in any other type of light.
- D. Yellow light. Yellow light is a color of light that is in the visible spectrum. Photosynthesis takes place faster in white light than in yellow light.
