A plant exposed to light with a wavelength of about 430 nm will produce which substance more quickly than a plant of the same size and species exposed to equally bright light with a wavelength of about 550 nm?

Answer 1

A plant exposed to light with a wavelength of about 430 nm will produce glucose (or other carbohydrates) more quickly than a plant of the same size and species exposed to equally bright light with a wavelength of about 550 nm. This is because light at 430 nm falls within the blue light spectrum, which is more effective for photosynthesis than green light at 550 nm. Plants absorb blue light more efficiently, leading to higher rates of photosynthetic activity and, consequently, increased production of glucose.
