Absorption and Upward Movement of Water and Minerals
Absorption and Upward Movement of Water and Minerals: Overview
In this topic, we will learn the concept of absorption and upward movement of water in detail. We will study the five main phenomena including imbibition, diffusion, osmosis, active transport and turgidity.
