Revision Notes For For Class 11 Biology Chapter 13 Photosynthesis In Higher Plants

Photosynthesis is the biological process used by plants to convert light energy into chemical energy. In this process, carbon dioxide and water molecules are converted into simple sugar glucose required by the plants for their growth and development by releasing out the oxygen molecules into the atmosphere.

CBSE Notes Class 11 Biology Chapter 13 Photosynthesis in Higher Plants

The entire process of photosynthesis takes place in the chloroplast of the cell and 4 different types of pigments present within the leaves are involved in this process. There are two different types of Photosynthetic Reactions:

  • Light Dependent Reaction
  • Light Independent Reaction

Frequently asked Questions on CBSE Class 11 Biology Notes Chapter 13: Photosynthesis in Higher Plants


What is a ‘Light dependent’ reaction?

The light dependent reaction is a photochemical reaction taking place in the thylakoid membranes of chloroplasts.


What is ‘Calvin cycle’?

Calvin cycle is also known as the C3 cycle. It is the cycle of chemical reactions where the carbon from the carbon cycle is fixed into sugars.


What are ‘Dark Reactions’?

Dark Reactions are a series of chemical reactions in photosynthesis not requiring the presence of light and involving the reduction of carbon dioxide to form carbohydrate.
