Photosynthesis in Higher Plants Class 11 Notes – Chapter 13
Photosynthesis is a process by which plants create their own food by using sunlight. This process was first seen more than 3.4 billion years ago in organisms that were similar to bacteria. Evidence showed that they did not absorb visible light, instead, they used near-infrared and produced sulphur or sulphate compounds. It would be another 470 million years until the first land plants emerged. Please refer Photosynthesis in Higher Plants Class 11 Notes for more revision notes.
