Lysosomes are important to eukaryotic cells because they contain
A) photosynthetic pigments.
B) starch molecules for energy storage.
C) their own DNA molecules.
D) the cells' waste materials.
E) digestive enzymes.

Question

Quizplus · Accepted Answer

Lysosomes contain digestive enzymes that break down macromolecules, old cell parts, and foreign substances that enter the cell. This helps to keep the cell clean and free of debris, which is necessary for its proper function. The other choices are incorrect because photosynthetic pigments are found in chloroplasts, starch molecules are stored in plastids, and the cell's waste materials are found in vacuoles or transported out of the cell. Lysosomes do not have their own DNA molecules.
