The Cellular Defense Against Viruses

The video explains how cells function, starting with a virus entering the body and how cells respond by producing antibodies. It covers the structure and function of cell membranes, the role of the nucleus in creating messenger RNA, and the process of antibody production involving ribosomes and the golgi apparatus. The video also discusses how cells generate energy through mitochondria and chloroplasts, highlighting the cooperation of cell parts to maintain body function.

What is the primary function of the cell membrane?

• To produce energy for the cell

• To protect and surround the cell's inner components

• To create antibodies

• To generate oxygen

What is unique about plant cells compared to animal cells?

• Containing mitochondria

• Having a cell wall made of cellulose

• Ability to produce antibodies

• Presence of a cell membrane

How does a virus initially deceive a cell to gain entry?

• By disguising as a nutrient

• By breaking through the cell wall

• By attaching to a cell membrane projection pretending to be a friend

• By directly entering the nucleus

What is the role of messenger RNA in the production of antibodies?

• To form the cell membrane

• To destroy the virus directly

• To transport instructions from the DNA

• To create energy molecules

Where are antibodies created within a cell?

• At the ribosome

• In the mitochondria

• Inside the nucleus

• In the golgi apparatus

What is the function of the Golgi apparatus in the immune response?

• To create amino acids

• To produce messenger RNA

• To generate ATP

• To package and direct antibodies

What molecule do mitochondria produce to power cell functions?

• Chlorophyll

• Ribosomes

• DNA

• ATP

What is the main reason humans breathe oxygen?

• To cool down the body

• To assist mitochondria in producing energy

• For digestion

• To aid in speech

How do plant cells produce energy?

• By breaking down sugar molecules

• Through the use of mitochondria

• By consuming oxygen

• Using chloroplasts to convert sunlight into chemical energy

How many cells are estimated to be in the human body?

• About 37 thousand

• About 37 trillion

• About 37 billion

• About 37 million
