Which accurately explains the functions of the organelles lysosomes? They:
A) Are sacs filled with enzymes that breakdown and remove foreign substances and worn-out cell parts
B) Function in association with the endoplasmic reticulum to modify protein end products and package them into secretory granules or vesicles
C) Are small particles of nucleoproteins that are involved in the synthesis of proteins that remain in the cell as cytoplasmic structural or functional elements
D) Are a dynamic system of interconnected membranous tubes that functions as a tubular communication system for transporting various substances from one part of the cell to another
Ans: A
Feedback:
Lysosomes are sacs that are filled with hydrolytic enzymes that aid in the processing and removal of unwanted substances within the cytoplasm. The Golgi apparatus functions in association with the endoplasmic reticulum to modify and package substances in preparation for secretion, whereas ribosomes are small particles of nucleoproteins that are involved in the synthesis of proteins. The ER is a tubular communication system for transporting various substances from one part of the cell to another.
