Explanation / Answer

2) 400nm

Plants use light of wavelength between 400-700nm

3) 400

4) A. This basically depends on day length

5) ATP and NADPH

6) A. It uses carbons dioxide and water to produce oxygen and sugar

7) sister chromatids which are connected by one centromere

8) A

Interphase occurs between two mitosis
