In an experiment, a researcher counts the number of oxygen bubbles produced by water plants placed under different colors of light. the researcher finds that water plants placed under white light release more oxygen bubbles than water plants placed under red light. which of the following statements is best supported based on the observation?

a. light can break up water molecules to form oxygen.

b. white light increases photosynthesis in plants.

c. red light has no affect on the release of oxygen from water plants.

d. an increase in temperature decreases the amount of oxygen produced by plants.

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.

essentially, one bacterial cell splits into two daugurer cells. bacterial offspring don't need or get care from their parents because they are in a sense their own parents. that said, some bacteria can and do depend on other bacteria especially in harsh environments such as bacterial microfilms in hot water tanks.
