WebIn all phototrophic eukaryotes, photosynthesis takes place inside a chloroplast, an organelle that arose in eukaryotes by endosymbiosis of a photosynthetic bacterium (see Unique Characteristics of Eukaryotic Cells ). These chloroplasts are enclosed by a double membrane with inner and outer layers. Within the chloroplast is a third membrane that ... WebIf an organism could be grown on an agar plate or in a liquid culture, then it could be studied, analyzed, and added to our growing catalog of prokaryotic species and strains. Some prokaryotes, however, can't grow in a laboratory setting (at least, not under the conditions scientists have tried).
