Estimating relative CO2 consumption or O2 release during photosynthesis at different wavelengths of light, is termed as:
Correct answer: A. Action spectrum
- A. Action spectrum
- B. Absorption spectrum
- C. Dark reaction
- D. Light reaction
Explanation
Action spectra show the effectiveness of different colors of light for carrying out photosynthesis measured by CO2 consumption or O2 release. Absorption Spectrum, on the other hand, is a graphical representation of the amount of light of different wavelengths absorbed by a pigment.

About Plant Nutrition and Transport
Plants require macronutrients and micronutrients for growth, and mineral deficiencies produce recognizable symptoms. Transport involves water and minerals through xylem by transpiration pull, cohesion and adhesion, while phloem translocates sugars from sources to sinks. Root pressure and transpiration are distinct mechanisms.
