QUESTION1 True or False: Light independent reactions tilize pigments, involve the electron transport system, and are relatively fast reactions. O True O False QUESTION 2 What is the advantage of having more than one type of photosynthetic pigment? a. All of the different pigments must be present for photosynthesis to occur o b. Carotenoids pigments contain a chemical that accelerates the process of photosynthesis O c. The different pigments absorb different wavelengths of light o d. The different pigments lead to the synthesis of different types of sugars

Explanation / Answer

Answer

1. False. Light independent reaction not uses pigments and ETC it is a calvin pathway used to synthesis the glucose molecule. only light dependent reaction uses pigments and ETC for produce NADPH and ATP molecules.

2. The different pigments absorb different wavelength of light.

From sunlight the visible range 400 - 800nm. So if the plant have different pigments means it will absorb the wavelength at different scale and it useful for plant photosynthesis.
