WebAug 2, 2014 · Chloroplasts were once free-living bacteria! Chloroplasts entered a symbiotic (Greek syn = together, and bios = life) relationship with another cell, which eventually led to the plant cells we have today. WebIn plant cells, chloroplasts may be moved around with the stream, possibly to a position of optimum light absorption for photosynthesis. The rate of motion is usually affected by light exposure, temperature, and pH levels. The optimal pH at which cytoplasmic streaming is highest, is achieved at neutral pH and decreases at both low and high pH. WebDo bacterial cells not contain chloroplasts?
