What we expect you to know
Terminology
You should know, what these terms mean and you should be able to explain them in your own words.
Plastids . Chloroplast . Chromoplast . Amyloplast . Proplastid . Stroma . Thylakoids . Signal peptide . Chlorophyll . Carotinoids . transitorial starch . Secondary metabolism . endosymbiont theory . Stromules
Content
-
You can draw and explain the structure of a plastid
-
You can show in this drawing, where light and dark reaction and ATP synthesis are located
-
You can name the developmental and functional variants of plastids properly
-
You can explain the evidence for the endosymbiotic origin of plastids
-
You can explain the core of the stromule theory and its falsification in your own words
Vertiefung (for Bachelor students)
- 1. Take the sum formula of photosynthesis and divide it up into two formula, one for the thylakoid, the other for the stroma.
- 2. How would the proton gradient from thylakoid lumen to stroma change in a mutant, where plastoquinone has lost function?
- 3. In what chemical form does a C4 plant get carbon dioxide into the bundle sheath, in what form does the carrier get back into the mesophyll? Sketch down the molecules and highlight the difference
- 4. In the extensive Cyperus genus, C3 and C4 clades coexist. You find a new Cyperus species in the field (there are >1000!). How can you easily assign them to C3 versus C4?
- 5. What would be the phenotype of a plant, where FtsZ has suffered a loss-of-function?
- 6. What do you expect for the expression of jasmonate induced genes when you block the expression of JASSY by RNai?
