TED-Ed: Cell vs. virus: A battle for health - Shannon Stiles

The video explains how cells function and respond to viral infections. It begins with an overview of cells, their structure, and how viruses can invade them. The immune response is detailed, highlighting how cells produce antibodies to fight viruses. The process of protein synthesis is explained, including the roles of the nucleus, ribosomes, and the golgi apparatus. Finally, the video covers how cells generate energy, focusing on mitochondria in animal cells and chloroplasts in plant cells.

What is the primary function of the cell membrane?

• To allow all substances to enter the cell

• To create antibodies

• To protect the cell and regulate entry and exit of substances

• To produce energy for the cell

How does a cell initially respond when a virus enters?

• It creates a new cell wall

• It sends a signal to the brain

• It uses enzymes to break down the virus

• It immediately produces antibodies

Where does the process of making antibodies begin?

• In the golgi apparatus

• In the nucleus

• In the ribosome

• In the mitochondria

What role does the golgi apparatus play in antibody production?

• It generates energy for the cell

• It reads the DNA instructions

• It breaks down viruses

• It packages antibodies for delivery

How do plant cells generate energy differently from animal cells?

• They use chloroplasts to convert sunlight into chemical energy

• They do not require energy

• They use mitochondria to create ATP

• They rely on the golgi apparatus
