How are proteins normally transported into a plant cell’s chloroplast, if they were originally synthesized on ribosomes present in the cytosol (not on the rough endoplasmic reticulum)? A. they are packaged into vesicles with v-SNARES for fusion with their target organelles B. they can pass freely through large pores in the inner chloroplast membrane C. they are secreted by the Golgi, captured by receptors, and absorbed by endosomes D. they must pass through the nuclear envelope by means of nuclear pores E. they are unfolded in the translocation channel, then refolded by chaperones
