| Front | What is some supporting evidence for mass flow |
|---|---|
| Back | 1. If a ring of bark is removed from woody stem, a bulge forms above the ring. Fluid from bulge has higher concentration of sugars than fluid below the ring. 2. A radioactive tracer can be used to track movement of organic substances in plant 3. can use aphids, the aphids pierce the phloem, the body is removed leaving the mouth parts. Sap flows out quicker nearer the leaves than further down the stem 4. Use a metabolic inhibitor which stops ATP production then translocation stops |
