Understanding Viruses

The video explores whether viruses are considered living organisms, explaining that they are not due to their inability to reproduce independently, lack of cellular structure, and absence of vital functions. It details the reproduction process of viruses, including the lytic and lysogenic cycles. The video also discusses virus prevention, highlighting the role of vaccines and natural antivirals in supporting the immune system.

What is the significance of viruses in the context of the coronavirus pandemic?

• They have raised more questions about viruses.

• They are easily visible to the human eye.

• They are the largest infectious agents.

• They have become less relevant.

What does the Latin word 'virus' mean?

• Microorganism

Why are viruses not visible to the human eye?

• They do not exist.

• They are too large.

• They are microorganisms.

• They are transparent.

Which of the following is NOT a reason why viruses are not considered living beings?

• They lack vital functions like respiration and communication.

• They are not made up of cells.

• They can survive without a host.

• They cannot live and reproduce independently.

What do viruses need to reproduce?

• A host organism

• Oxygen

• Sunlight

• Water

In the lytic cycle, what happens to the host cell?

• It remains unaffected.

• It multiplies.

• It is destroyed.

• It becomes stronger.

During the lysogenic cycle, what do viruses do initially?

• Remain inactive

• Multiply rapidly

• Integrate their genome into the host cell's genome

• Destroy the host cell

What is the current status of vaccines for the coronavirus?
