Chapter 11 – Transport In Plants
Transport in Plants explains how water, minerals, and food are moved within plant bodies. This chapter mainly focuses on the processes of diffusion, facilitated diffusion, osmosis, active transport, transpiration, and translocation. Plants absorb water and minerals from the soil through roots and transport them upward through the xylem, while prepared food (sugars) is transported from leaves to other parts of the plant through the phloem.
The chapter also covers ascent of sap, transpiration pull theory, and mass flow hypothesis, which explain how substances move efficiently inside plants. Understanding this chapter is essential for Class 11 Biology students, especially for competitive exams like NEET, as it forms the foundation for plant physiology concepts.
