9.2 Transport in the phloem of plants: Phloem and Hydrostatic Gradients

Table of Contents:

00:00 - Transport in the phloem of plants
00:23 - Phloem
04:47 - Hydrostatic Pressure Gradients
08:44 - How sucrose gets “pumped”
08:47 - Hydrostatic Pressure Gradients
09:13 - How sucrose gets “pumped”
11:40 - Hydrostatic Pressure Gradients

Understanding that:

-Incompressibility of water allows transport along hydrostatic pressure gradients.
-Raised hydrostatic pressure causes the contents of the phloem to flow towards sinks.
