These structures are involved in the breakdown of old organelles:
Correct answer: B. Lysosomes
- A. Leucoplasts
- B. Lysosomes
- C. Glyoxysomes
- D. Peroxisomes
Explanation
Lysosomes are membrane-bound organelles containing hydrolytic enzymes that digest cellular waste, including old or damaged organelles, through a process known as autophagy. They play a crucial role in cellular maintenance and recycling. In contrast, leucoplasts are involved in storage, glyoxysomes in fatty acid conversion in plants, and peroxisomes in oxidative reactions, none of which involve the breakdown of organelles.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
