Living Cells and Viruses

The video explores the differences between cells and viruses, focusing on their reproduction, composition, energy use, and development. Cells reproduce through binary fission or mitosis, while viruses require a host cell to replicate. Cells are complex structures with organelles, whereas viruses consist of genetic material within a protein coat. Cells generate energy via mitochondria, but viruses rely on host cells for energy. Cell development is orderly, while virus development is rapid and destructive.

How do viruses reproduce compared to cells?

• Viruses reproduce independently like cells.

• Viruses require a host cell to reproduce.

• Viruses use binary fission to reproduce.

• Viruses reproduce through mitosis.

What is the main structural difference between cells and viruses?

• Viruses have mitochondria, cells do not.

• Cells have complex organelles, viruses have a protein coat.

• Viruses have organelles, cells do not.

• Cells have a capsid, viruses do not.

What powers the energy needs of a cell?

• The cell's capsid

• The cell's nucleus

• The cell's ribosomes

• The cell's mitochondria

How do viruses obtain energy?

• They rely on the host cell's energy.

• They have their own mitochondria.

• They generate their own energy.

• They use energy from the sun.

What happens to a cell when a virus replicates inside it?

• The cell divides normally.

• The cell becomes stronger.

• The cell bursts and releases new viruses.

• The cell repairs itself.
