Unformatted text preview: nsla3onal inser3on of proteins into endoplasmic re3culum. Chloroplast Structure Fig. 14- 25b Stroma Fig. 14- 25C Fig. 14- 26 Primary light harves:ng pigment in chloroplasts? Figure 14- 30 (14- 33 2nd edi3on) Any other pigments in the chloroplast? e.g. β- carotene, Xanthophyll, lycopene Chloroplasts are the most prominent members of the plas3d family of organelles Plas3ds can differen3ate according to the role they perform E3oplast Chloroplast Proplas3d Amyloplast Chromoplast A proplas3d from a bean root 3p cell Plas:ds are also sites for synthesis of Purines & Pyrimidines, most amino acids, and all faNy acid in plants Gravity sensing amyloplast from root 3p An e3oplast from a dark grown leaf Chromoplasts in Red pepper fruit Chromoplasts, Carotenoids & Anthocyanins in Fall Foliage Based on these images, which of these cells is photosynthe3c? C=BOTH A B Arabidopsis thaliana- stem epidermis Fig. 14- 28 (14- 32 2nd ed): Stages of photosynthesis Light dependant reac:ons Light independent reac:ons Figure 14- 28 Essen&al Cell Biology (© Garland Science 2010) The light dependant reac:ons harvest light energy and transform it into a form than can be used by the cell light dependant (Light Rxns) light independant (Dark Rxns) Compare this image to the equivalent image of a mitochondrion in this l...
