Question

question 27 of 32
a certain organelle is part of the endomembrane system of a cell and looks like flattened sacs of membranes. it is often referr to as the \post office\ of the cell because it sorts, modifies, and repackages proteins and lipids. it then ships the products in vesicles to other parts of the cell or to the plasma membrane, where they may exit the cell. however, this organelle does not participate in the synthesis of proteins and lipids.

identify this organelle.
golgi apparatus
lysosome
mitochondrion
nucleus

Explanation:

The organelle described is part of the endomembrane system, has flattened membrane sacs, acts as the "post office" by sorting/modifying/repackaging proteins/lipids, ships them in vesicles, and does not synthesize these molecules—all key features of the Golgi apparatus. Lysosomes digest materials, mitochondria produce energy, and the nucleus stores genetic material, so they do not match the description.

Answer:

Golgi apparatus
