Q34 / 200 · NEET 2002 · Botany

Which of the following absorb light energy for photosynthesis?

  • Correct answer
    A
    Chlorophyll
  • B
    Water molecule
  • C
    $\mathrm{O}_2$
  • D
    RUBP

Solution

Chlorophyll molecule absorbs light for photosynthesis. $\mathrm{H}_2 \mathrm{O}$ molecules provide $\mathrm{H}^{+}$ions and electrons during photosynthesis. $\mathrm{O}_2$ is liberated during photosynthesis. RuBP (Ribulose 1, 5-bisphosphate) reacts with $\mathrm{CO}_2$ during dark reaction of photosynthesis. This process takes place in the presence of enzyme RuBisCO.

Hence, the correct answer is option: 'A'.
