The sufficient amount of sunlight stored in a cell

The device to utilize sun rays directly to meet the requirement of heat energy

Specify how a pentose phosphate is a CO 2 acceptor in the dark reaction of photosynthesis.

Pentose phosphate i.e. ribulose 1, 5-bisphosphate (RuBP) accepts the CO 2 in the first step of dark reaction or Calvin cycle. The pentose phosphate along with CO 2 undergoes carboxylation in the presence of an enzyme RuBisCO to form an unstable 6C containing molecule which splits and give 2 molecules of phosphoglyceric acid (PGA).
