Photosynthesis can only occur with specific wavelengths of light. The light reacts with the aromatic ring of a specific chlorophyll(different ones in different plants) molecules. The structure of this molecule creates different energy fields for the electrons in the aromatic ring. The distance between these energy fields is quantized and therefore can only take specific energies of light(wavelengths). This energy is then used to reduce NADP+ to NADPH. This reducing equivalent can then be used to reduce several molecules of CO2 which can be combined to form glucose. This results in the fact that if you deprive plants of specific wavelengths of light they will die.

How does the wavelength of light affect the process of photosynthesis?
The wavelength of light affects photosynthesis by determining the amount of energy available for the process. Different wavelengths of light provide different amounts of energy, with red and blue light being most effective for photosynthesis. This energy is used by plants to convert carbon dioxide and water into glucose and oxygen.
What are some factors that affect photosynthesis?
Some factors that affect photosynthesis include light intensity, carbon dioxide levels, temperature, and water availability. Changes in any of these factors can impact the rate of photosynthesis in plants.
Does the type of light affect photosynthesis?
Yes, the type of light does affect photosynthesis. Different wavelengths of light can impact the rate of photosynthesis in plants. Blue and red light are most effective for photosynthesis, while green light is less effective because it is reflected rather than absorbed by plants.
What is the significance of the chlorophyll optimum wavelength in relation to photosynthesis?
The chlorophyll optimum wavelength is important for photosynthesis because it is the specific range of light wavelengths that chlorophyll molecules absorb most efficiently. This allows plants to capture and convert light energy into chemical energy more effectively, ultimately driving the process of photosynthesis.
What wavelength of light is the least effective in driving photosynthesis?
Green light is the least effective in driving photosynthesis because chlorophyll pigments absorb more strongly in the blue and red regions of the spectrum. This results in green light being poorly absorbed and utilized for photosynthesis in plants.
How does the wavelength of light affect the process of photosynthesis?
The wavelength of light affects photosynthesis by determining the amount of energy available for the process. Different wavelengths of light provide different amounts of energy, with red and blue light being most effective for photosynthesis. This energy is used by plants to convert carbon dioxide and water into glucose and oxygen.
What is the significance of the wavelength 680 nm in the context of photosynthesis?
The significance of the wavelength 680 nm in photosynthesis is that it corresponds to the peak absorption of light by chlorophyll a, the primary pigment responsible for capturing light energy during the light-dependent reactions of photosynthesis. This specific wavelength is optimal for driving the process of photosynthesis and converting light energy into chemical energy.
What are some factors that affect photosynthesis?
Some factors that affect photosynthesis include light intensity, carbon dioxide levels, temperature, and water availability. Changes in any of these factors can impact the rate of photosynthesis in plants.
Is light with long wavelengths good for photosynthesis?
No. Unless the wavelength of the light is sufficient to excite the reaction, no amount of longer wavelength light will do anything except add to local heating.
How will light affect photosynthesis?
Light allows photosynthesis to occur. Therefore more light=faster reaction.
How does wavelength affect visible light?
It alters the energy and colour of the light.
How do different pigments colors affect the rate of photosynthesis?
The wavelength of a color is directly related to the rate of photosynthesis, with longer wavelengths leading to higher rates of photosynthesis.
Which light has the least affect on photosynthesis?
Green light has the least effect on photosynthesis because it is poorly absorbed by chlorophyll, which is the pigment responsible for capturing light energy during photosynthesis. This means that plants do not use green light as efficiently as other colors for photosynthesis.
Does the type of light affect photosynthesis?
Yes, the type of light does affect photosynthesis. Different wavelengths of light can impact the rate of photosynthesis in plants. Blue and red light are most effective for photosynthesis, while green light is less effective because it is reflected rather than absorbed by plants.
Does the wavelength of light a plant is exposed to affect plant?
Yes.
What are some examples of wavelength questions that can be used to investigate the properties of light?
Some examples of wavelength questions to investigate the properties of light include: How does the wavelength of light affect its color perception? What is the relationship between the wavelength of light and its energy? How does the wavelength of light impact its ability to be refracted or diffracted? How does the wavelength of light influence its interaction with different materials, such as glass or water?
What is the testable question for light?
How does the intensity of light affect the rate of photosynthesis in plants?
