WebOct 31, 2024 · What kind of bundle sheath cells does cassava have? Cassava leaves contain green bundle-sheath cells, characteristic of C4 plants, although not with typical C4 leaf ‘Kranz anatomy’ and express activity of the key C4 enzymes, phosphoenolpyruvate carboxylase and phospho-glycolate phosphatase ( El-Sharkawy et al., 2008 ). Web- have bundle sheath cells and mesophyll cells - bundle sheath: packed sheaths around veins of leaf - mesophyll cells: between the bundle sheath and the leaf surface - calvin …
WebSolution. A) Bundle sheath cells are rich in RuBisCO. B) Mesophyll cells lack RuBisCO and Bundle sheath cells are rich in RuBisCO and lack PEP carboxylase. C) Bundle sheath cells are rich in RuBisCO and lack PEP carboxylase. D) Mesophyll cells are rich in PEP carboxylase. So the correct answer is 'Are rich in RuBisCO'. WebMay 14, 2024 · Bundle sheath cells are deep in the leaf so atmospheric oxygen cannot diffuse easily to them and often have thylakoids with reduced photosystem II complexes (the one that produces O 2). Both of these features keep oxygen levels low in Bundle sheath cells, which is where the 4-carbon compound is broken down into carbon dioxide, which …
