7 Main Mechanisms of Phloem Transport in Plants
The following points highlight the seven main mechanisms of phloem transport in plants. The mechanisms are: 1. Pressure Flow 2. Diffusion 3. Cyclosis 4. Electro-Osmosis 5. Transcellular Streaming 6. Microfibrillar Model 7. Correlation of Structure and Function. Mechanism # 1. Pressure Flow: According to this hypothesis the metabolites transport is a physical phenomenon (Fig. 26-7). The bulb A has strong whereas [...]
