The Cell: the Nucleus

The video explains how the brain and cells have control centers, with the nucleus acting as the cell's brain, regulating activities. The nuclear membrane protects the nucleus, allowing selective material passage. The nucleolus, within the nucleus, is responsible for building RNA and creating ribosome components.

What is the primary role of the nucleus in a cell?

• To protect the cell from external damage

• To transport materials within the cell

• To regulate all cellular activities

• To provide energy to the cell

Which structure acts as the cell's brain?

• Mitochondria

• Nucleus

• Ribosome

• Cell membrane

How does the nuclear membrane function in relation to the nucleus?

• It generates energy for the nucleus

• It allows all materials to freely pass in and out

• It selectively permits materials to enter and exit

• It stores genetic information

What is the similarity between the nuclear membrane and the cell membrane?

• Both are involved in protein synthesis

• Both store genetic material

• Both generate energy

• Both selectively allow materials to pass

What is the nucleolus primarily responsible for?

• Regulating cell division

• Storing nutrients

• Creating ribosome components

• Building DNA
