Which events take place in the light-dependent reactions of photosynthesis?
light energy is converted sugars; sugars are broken down for energy.

light energy is captured by plants; light energy is used to make sugar.

light energy is converted to chemical energy; chemical energy is used to make sugar.

light energy is captured by plants; light energy is converted to chemical energy.

The correct answer is : Light energy is captured by plants; light energy is converted to chemical energy.

In the process of photosynthesis, special pigment molecule called chlorophyll can capture the energy of the light, more specifically the photon. When a particle of light (a photon) with a specific energy reaches this pigment in the leaves of plants, the energy is transferred from the particle to the molecule, and the molecule becomes excited. This is the phase where the energy of the light is captured and transformed into chemical energy that can later be used to make sugars.

All of the later chemical processes that transfer the energy from the excited chlorophyll to the sugar molecules are not dependent on the light and can happen during the night as well.
