Answer:
B. White light increases photosynthesis in plants.
Explanation:
Photosynthesis in simple term is defined as the process an organism uses the energy got from light in order to utilise CO2 and H2O for the production of glucose/organic matter and O2 as a gas. Examples of these organisms include,
plants, bacteria etc
6CO2 + 6H2O --> C6H12O6 + 6O2
Light can be absorbed by pigments in the oragnism cell like chlorophyll. Different pigments absorb different wavelengths of light. Leaves of a plant are green because the chlorophyll within them absorb all the other wavelengths of light in the spectrum and reflects green light. Absorption spectrum shows that red and violet light are the most absorbed whereas green light is most reflected.
A white light has maximum photosynthesis because white light is polychromatic i.e of varying colours so it could absorb blue, red, violet etc.
So therefore, White light increases photosynthesis in plants.
answer; Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. ... Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation. Updated January 06, 2020. A gene is a portion of DNA that determines a trait. A trait is a characteristic, or a feature, passed from one generation to another, like height or eye color. Genes come in multiple forms or versions. Each of these forms is called an allele
