Biology - Photosynthesis in Higher Plants

Practise 12 NEST (NISER) previous year questions on Photosynthesis in Higher Plants, compiled from papers spanning 2011 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty NEST (NISER) tests.

Photosynthesis in Higher Plants has been asked in 8 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 12 questions in all. 0% of them were easy, 100% moderate and 0% tough. Most of its questions came from 2024, with 3 questions that year. In the last three years (2024–2026) it had 4 questions across 4 papers, about 1 per paper.

The chapter's 4 topics are not weighted equally: Mechanism of Photosynthesis (9 questions, 75%), Pigments (1 question, 8%), and Factor Affecting Photosynthesis (1 question, 8%) have been asked the most. Mechanism of Photosynthesis has also led over the last five years, with 5 questions.
