Biology - Transport in Plants

Practise 7 NEST (NISER) previous year questions on Transport in Plants, compiled from papers spanning 2013 to 2026. 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.

Transport in Plants has been asked in 6 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 7 questions in all. 14% of them were easy, 86% moderate and 0% tough. Most of its questions came from 2025, with 2 questions that year. In the last three years (2024–2026) it had 3 questions across 4 papers, about 0.8 per paper.

The chapter's 4 topics are not weighted equally: Plant Water Relations (2 questions, 29%), Mass Flow Hypothesis (2 questions, 29%), and Transpiration (2 questions, 29%) have been asked the most. Plant Water Relations has also led over the last five years, with 1 question.
