strikes the photosystems that consist of many secondary chlorophyll and b karotenes which pass the energy to the reaction centre which is a primary chlorophyll.
Sunlight excites electrons in chlorophyll during the process of photosynthesis, where they are used to convert carbon dioxide and water into glucose and oxygen. This excitation of electrons is a key step in converting light energy into chemical energy that the plant can use for growth and metabolism.
The energy that excites electrons in chlorophyll comes from sunlight. Specifically, chlorophyll absorbs light energy from the sun, which is then used to power the process of photosynthesis.
The unit of hundreds of chlorophyll molecules that trap the energy of sunlight is typically referred to as a "photosystem." In plants, these photosystems, primarily Photosystem I and Photosystem II, contain clusters of chlorophyll molecules that work together to capture light energy during photosynthesis.
When sunlight hits the leaves, the energy from the light is absorbed by chlorophyll, the green pigment in the chloroplasts. This absorbed energy excites electrons in the chlorophyll molecules, raising them to a higher energy state. These high-energy electrons are then transferred through a series of proteins in the thylakoid membrane, initiating the process of photosynthesis, which ultimately converts light energy into chemical energy stored in glucose.
In Photosystem II, electrons excited by sunlight are replaced by electrons derived from the splitting of water molecules (photolysis). This process releases oxygen as a byproduct and provides the necessary electrons to replenish those lost by the chlorophyll when it absorbs light energy. In Photosystem I, the excited electrons are eventually transferred to NADP+, forming NADPH, which is crucial for the Calvin cycle in photosynthesis.
Electrons in photosystem II get their energy from sunlight. When photons from sunlight are absorbed by the chlorophyll molecules in the photosystem, the energy is transferred to electrons, allowing them to become excited and drive the process of photosynthesis.
After sunlight hits Photosystem II, it energizes the electrons in the chlorophyll molecules. The energized electrons are then passed through an electron transport chain, generating ATP and NADPH molecules through the process of photophosphorylation.
the electrons gain a huge amount of energy
At first, sunlight causes an increase in photosynthesis. At some point, photosynthesis stops increasing with increasing sunlight. At this point, the chlorophyll molecules are saturated. Further increases in sunlight cause a decrease in photosynthesis as chlorophyll molecules are destroyed.
The reactant in the process powered by sunlight hitting photosystem 2 is water. In this process, water is split into oxygen, protons, and electrons when sunlight is absorbed by chlorophyll molecules.

Sunlight excites electrons in chlorophyll during the process of photosynthesis, where they are used to convert carbon dioxide and water into glucose and oxygen. This excitation of electrons is a key step in converting light energy into chemical energy that the plant can use for growth and metabolism.
