BIOL 220 Lecture Notes - Lecture 12: Sieve Tube Element, Plant Morphology, Electrochemical Gradient
Document Summary
Examine link between soil type, ph and water status in nutrient availability. Make predictions in plant growth patterns in varying soil conditions. Describe role of membrane proteins in moving sugars. Describe mechanisms that plant uses to take in inorganic nutrients from the soil and how it can enhance this uptake. Explain how sugars are transported from their source of their destination (sink) Examples of sources and sinks: carrot -biennial plant, source-photosynthesis leaves, sink-roppt=orange )regular carrot=1st ear, second year it looks like flower. On second year source of sugar is the rootsstoring sugar so it can do this the next year"ssink is flower/fruits in second year: phloem can run in either direction, depends on where you"re loading and. Identify the source and sink for each of the following plants unloading, the pressure potential: deciduous tree in summer, deciduous tree in spring, seed planted one inch below surface, rapidly growing plant, plant producing flowers.
