Final answer:
The Golgi apparatus cannot receive proteins directly from the cytosol; instead, it receives proteins from the endoplasmic reticulum (ER), which are then modified and sorted for distribution within the cell or secretion.
Step-by-step explanation:
The organelle that cannot receive proteins directly from the cytosol is the Golgi apparatus. Proteins synthesized in the cytoplasm are typically transported to organelles such as the chloroplast, mitochondrion, peroxisome, or nucleus, where they contain specific signal sequences that direct them to their correct destinations. However, the Golgi apparatus functions differently; it receives proteins from the endoplasmic reticulum (ER) rather than directly from the cytosol. These proteins first enter the ER, where they are folded and modified. Afterward, they are packaged into vesicles that then transport them to the Golgi apparatus for further modification, sorting, and distribution.
