what part of the electromagnetic spectrum do plants use for photosynthesis?
257228
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).

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
318566
Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. The process of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic compounds and oxygen.

Stars like our Sun emit most of their light in which part of the electromagnetic spectrum? The two forms of electromagnetic radiation that penetrate the atmosphere best are: visible and radio waves.
1419652
The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.
21527
Green light is considered the least efficient wavelength in the visible spectrum for photosynthesis, but it is still useful in photosynthesis and regulates plant architecture.
745753
Infrared (Wavelength ~ 10-6 to 10-3 meters) Infrared radiation is used extensively in remote sensing. Objects reflect, transmit, and absorb the Sun's near-infrared and shortwave radiation in unique ways and this can used to observe the health of vegetation, soil composition and moisture content.

Green plants are able to use photosynthesis to take carbon dioxide, water and energy from the sun and convert it into chemical energy. It converts these compounds into oxygen, which is released into the atmosphere, and organics, like sugar.

Full-spectrum light is light that covers the electromagnetic spectrum from infrared to near-ultraviolet, or all wavelengths that are useful to plant or animal life; in particular, sunlight is considered full spectrum, even though the solar spectral distribution reaching Earth changes with time of day, latitude, and ...
479378
For photosynthesis to take place, plants need to take in carbon dioxide (from the air), water (from the ground) and light (usually from the sun).
247726
Nearly all frequencies and wavelengths of electromagnetic radiation can be used for spectroscopy. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation.

What organisms perform photosynthesis? Autotrophs; plants, algae, and some bacteria.
900945
Chlorophyll absorbs light most strongly in the blue portion of the electromagnetic spectrum, followed by the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum, hence the green color of chlorophyll-containing tissues.

Photosystem OR Photosynthetic Reaction Center (PRC) is known as functional unit of photosynthesis. ... Light harvesting complex OR Antenna molecules are used by plants and photosynthetic bacteria to collect more of the incoming light and transfer it to the PS molecule.

Photosynthesis. ... Photosynthesis is the conversion of light energy into chemical energy by living organisms. The raw materials are carbon dioxide and water; the energy source is sunlight; and the end-products are oxygen and (energy rich) carbohydrates, for example sucrose and starch.
1180796
The major limiting factors for photosynthesis are light intensity, temperature, and carbon dioxide levels.
421405
All photosynthetic organisms contain a pigment called chlorophyll a, which humans see as the common green color associated with plants. Chlorophyll a absorbs wavelengths from either end of the visible spectrum (blue and red), but not from green.
