Question

The sun's energy is delivered as discrete packets that travel as waves and are called ________.

1) ATP.
2) carotenoids.
3) NADP.
4) photons.

Answer 1

The sun's energy consists of mass-less packets called photons, which play a crucial role in photosynthesis.

Step-by-step explanation:

The sun's energy is delivered as discrete packets that travel as waves and are called photons. These mass-less packets of energy are part of the electromagnetic spectrum and are involved in processes such as photosynthesis. In the light-dependent reactions of photosynthesis, photons are absorbed by photosystems and their energy is used to generate ATP and NADPH, which are energy carriers that drive the synthesis of sugar through the Calvin cycle.
