Answers:Cytopolasmic streaming is when the chloroplasts move around in the cytoplasm. They actually are travelling along tracks made of the microtubules from the cytoskeleton. There are "motor proteins" associated with these tracks that help move things around.
Answers:The movement of chloroplasts around the inside of the cell is called "cytoplasmic streaming", and is a way to ensure that all of the chloroplasts are exposed to sunlight, maximizing the efficiency of photosynthesis. Otherwise, the chloroplasts on the side of the cell away from the sunlight would be shaded by the cell's organelles.
Answers:Light is constantly being absorbed by the chloroplasts. But each chloroplast can only absorb so much light. Once a chloroplast is at maximum capacity, the light will penetrate to the other chloroplast and cells.
Answers:Although mitochondria and chloroplasts are enclosed by membranes, they are not part of the endomembrane system. In contrast to organelles of the endomembrane system, each of these organelles has at least two membranes separating the innermost space from the cytosol. Their membrane proteins are made not by the ER, but by free ribosomes in the cytosol and by ribosomes contained within these organelles themselves. Not only do these organelles have ribosomes, but they also contain a small amount of DNA (which supports the endosymbiotic theory). It is this DNA that programs the synthesis of the proteins made on the organelle s own ribosomes. (Proteins imported from the cytosol constituting most of the organelle s proteins are programmed by nuclear DNA.) Mitochondria and chloroplasts are semiautonomous organelles that grow and reproduce within the cell. Both also make ATP.
