Oof Thank Chu :3

C. Endoplasmic Reticulum

I think its C. Endoplasmic Reticulum bc the other person said

Thank u Njaos

You're welcome KOkai

You are correct! The organelle that breaks down organelles that are no longer useful is the lysosome (option B).

To determine the answer, we can first understand the functions of the organelles listed in the options:

A. Golgi Apparatus: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins and lipids into vesicles for transport within the cell or release outside the cell.

B. Lysosome: Lysosomes are membrane-bound organelles that contain enzymes capable of breaking down various biomolecules, including proteins, lipids, carbohydrates, and nucleic acids. They are known as the cell's "digestive system" and are involved in breaking down cellular waste and recycling materials.

C. Endoplasmic Reticulum: The endoplasmic reticulum (ER) is involved in protein synthesis and lipid metabolism. It is responsible for the synthesis, folding, and modification of proteins.

D. Mitochondrion: Mitochondria are the powerhouses of the cell, producing energy in the form of ATP through cellular respiration.

Given the functions of these organelles, it becomes clear that the lysosome (option B) is responsible for breaking down organelles that are no longer useful. Lysosomes contain digestive enzymes that can break down various cellular components, including worn-out organelles and cellular debris. Therefore, option B, the lysosome, is the correct answer.
