what two colors in the visible light spectrum are used in photosynthesis?
449967
Answer 2: The color of light used for photosynthesis depends on the pigment in the plant. For example, green plants with chlorophylls and carotenoids have a maximum activity with violet-blue and red light.

When it comes to light waves, violet is the highest energy color and red is the lowest energy color. Related to the energy and frequency is the wavelength, or the distance between corresponding points on subsequent waves. You can measure wavelength from peak to peak or from trough to trough.

Chlorophyll a absorbs light with wavelengths of 430nm(blue) and 662nm(red). It reflects green light strongly so it appears green to us. It contains a hydrophobic (fat soluble) phytol chain that allow it to be embedded in a lipid membrane.

The electromagnetic spectrum: Light The region between 400 nm and 700 nm is what plants use to drive photosynthesis and is typically referred to as Photosynthetically Active Radiation (PAR).

Photosynthetic cells contain special pigments that absorb light energy. ... Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.
617476
Photosynthesis is the process by which plants make food from light, water, nutrients, and carbon dioxide.

The key difference between chlorophyll and carotenoids is that the chlorophyll is a family of green colour pigments primarily used for photosynthesis in photosynthetic organisms while the carotenoids are a group of yellow to red colour pigments including carotenes and xanthophylls that are accessory pigments.

Maybe the most fascinating characteristic of visible light is color. Humans see a broad range of colors in visible light, and each color has its own corresponding wavelength. The color components of visible light include violet, blue, green, yellow to orange, bright red and dark red.

The Visible Spectrum White light is visible light, and it contains all the colors of the rainbow, from red to violet. The range of visible wavelengths is 400 to 700 nanometers. Ultraviolet light is the radiation from the sun that causes a sunburn when you have been outside too long on a sunny day.

As a general recommendation, choose a full spectrum grow light with a color temperature in the blue range (5,000 - 7,000K) to promote vegetative growth and choose a color temperature in the red range (3,500 - 4,500K) to promote fruiting and flowering. Visible Light Spectrum.

The measure of photochemical efficiency is made by meauring the amount of oxygen produced by leaves following exposure to various wavelengths. It is evident from these absorption and output plots that only the red and blue ends of the visible part of the electromagnetic spectrum are used by plants in photosynthesis.

Chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria. Chlorophyll is vital for photosynthesis, it allows plants to absorb energy from light. Iodine solution is not required for photosynthesis.

Visible light ranges from low blue to far-red light and is described as the wavelengths between 380 nm and 750 nm, although this varies between individuals. The region between 400 nm and 700 nm is what plants use to drive photosynthesis and is typically referred to as Photosynthetically Active Radiation (PAR).

blue light has the highest energy from the following options. In a spectrum, the violet colour has the "highest energy" and red colour has the "lowest energy".
405702
Photosynthesis occurs in two stages. During the first stage, the energy from sunlight is absorbed by the chloroplast. Water is used, and oxygen is produced during this part of the process. During the second stage, carbon dioxide is used, and glucose is produced.

The part of the solar spectrum used by plants has an estimated mean wavelength of 570 nm; therefore, the energy of light used during photosynthesis is approximately 28,600/570, or 50 kcal per einstein.
