Question

When chlorophyll absorbs light, it gets excited and emits (releases)

• A. Oxygen
• B. Water
• C. Electrons
• D. Energy rich compounds.

Answer 1

The correct option is C Electrons

Photosynthesis takes place in the green leaves of plants and other green parts of plants like stem etc. When chlorophyll absorbs light, it gets excited and emits electrons. These chlorophylls are found in photosynthetic units called Photosystem I and Photosystem II. Each unit has a specific reaction center which contains pigment molecules. These molecules absorb light of different wavelengths and emit electrons. These electrons are picked up by an electron acceptor which passes them to an electron transport system of cytochromes.
