Question

Based on your knowledge of energy flow and light absorption, which color(s) of light will provide energy for photosynthesis? (select all that apply) question 2 options: red orange green blue violet

Answer 1

Answer:

RED and BLUE

Explanation:

Special pigments in chloroplasts of plant cells absorb the energy of certain wavelengths of light, causing a molecular chain reaction known as the light-dependent reactions of photosynthesis. The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm).

Answer 2

Red and blue as the best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm).

Which colors of light are most absorbed for energy during photosynthesis?

Chlorophyll is the pigment responsible for photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light.

The chlorophyll pigments mainly absorb blue and red light. Maximum absorption is in blue light but maximum photosynthesis occurs in red light

Thus, the answer is red and blue.
