Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle packages up waste to be eliminated?
A
Golgi Complex
B
ribosomes
C
nucleus
D
Endoplasmic Reticulum
Explanation: 

Detailed explanation-1: -This sorting, tagging, packaging, and distribution takes place in the Golgi apparatus (Golgi body), an organelle made up of flattened discs of membrane.

Detailed explanation-2: -Golgi complex is mainly concerned with packaging and forming secretory vesicles for dispatch. In the plants it is involved in the formation of materials of cell wall (cellulose, hemicellulose, pectin and lignin etc). It is involved in the formation of glycoproteins, glycolipids, by glycosylation.

Detailed explanation-3: -Lysosomes are the garbage disposal units of our cells, roaming around digesting cellular waste with their specialized enzymes and recycling excess or worn-out cell parts. Additionally, they may also be used to destroy invading viruses and bacteria.

Detailed explanation-4: -Basically, the Golgi apparatus receives protein enzymes from the ER, which are packaged in a vesicle in the Golgi apparatus, processed and finally, pinched off as a Lysosome. Lysosomes then float in teh cytoplasm until they’re needed. Lysosomes rely on enzymes created in the cytosol and the endoplasmic reticulum.

Detailed explanation-5: -Cellular Recycling Bins: Lysosomes Lysosomes are produced in the Golgi and are membrane-enclosed sacs of hydrolytic enzymes that digest all major types of macromolecules. In short, worn-out materials floating around the cell are internalized and broken down by the lysosomes.
