Light dependent reactions of photosynthesis occur in Grana of the chloroplast. These were discovered by Robert Hill and hence known as Hill Reactions even. Was this helpful?
Light dependent Reactions. Light dependent reactions occur in the thylakoid membrane of the chloroplasts and take place only when light is available. During these reactions light energy is converted to chemical energy. 1  Chlorophyll and other pigments absorb energy from sunlight.2  Water is used to provide electrons and hydrogen ions but also produces oxygen. 3  The electrons and hydrogen ions are used to create ATP and NADPH.etâs take a look at how these are collected by plants. 1  Carbon dioxide from the air passes through small pores (holes) in the leaves. 2  Water is absorbed by the roots and passes through vessels in the stem on its way to the leaves. 3  Sunlight is absorbed by a green chemical in the leaves.
