Cell chloroplast
3.17: Chloroplasts. A typical plant cell (e.g., in the palisade layer of a leaf) might contain as many as 50 chloroplasts. A smooth outer membrane which is freely permeable to molecules. proteins synthesized in the cytoplasm of the cell but used within the chloroplast.The two-membrane chloroplast, observable under the microscope, is a key piece of evidence strengthening the theory that chloroplasts evolved when a eukaryotic cell captured a cyanobacteria and established Class Archaeplastida, the kingdom of plants. 4. The chloroplasts of non-Archaeplastida eukaryotes have three or four membrane layers.
