Answer:
X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm
Step-by-step explanation:
A bacterium is a living thing that are majorly known for causing diseases but are important for human life.
A bacterium is also consist of several organelles such as cell wall, cytoplasm, flagellum, bacterial DNA, cytoplasm, ribosomes and others.
The diagram shows three main organelles that are X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm. Flagella functions for the locomotion of the bacteria, bacterial DNA is a genetic material of the bacteria, and cytoplasm is a gel-like matrix composed of enzymes, water, nutrients and other waste material.
Hence, the correct answer is "X - Flagellum, Y - Bacterial DNA, Z - Cytoplasm".
