Transport in Plants explains how water, minerals, and food are moved within plant bodies to support growth and survival. This category focuses on the mechanisms of transport at cellular, tissue, and whole-plant levels, making it suitable for Class 11–12 students, NEET aspirants, and undergraduate learners.
In this section, you will study:
Diffusion, facilitated diffusion, and active transport
Water absorption by roots
Transpiration and its significance
Ascent of sap and theories explaining it
Structure and function of xylem and phloem
Translocation of food and the pressure flow hypothesis
Factors affecting transport processes in plants
NCERT-based explanations, diagrams, MCQs, and exam-oriented questions
The content is structured to build clear conceptual understanding, strengthen process-based reasoning, and help students perform confidently in school examinations, NEET, and undergraduate assessments.
Develop a strong understanding of transport mechanisms in plants and how they maintain internal balance and physiological function.
Q. What is the primary driving force for the movement of water in plants?
A.
Root pressure
B.
Capillary action
C.
Transpiration pull
D.
Soil moisture
Solution
Transpiration pull is the primary driving force for water movement in plants, created by the evaporation of water from leaf surfaces.
Q. What is the primary mechanism by which nutrients are absorbed by plant roots?
A.
Active transport
B.
Facilitated diffusion
C.
Endocytosis
D.
Simple diffusion
Solution
Active transport is the primary mechanism for nutrient absorption in plant roots, allowing plants to uptake minerals against their concentration gradient.
