Steel girders and framework

Question 9

Which organelle is most directly involved in the transport of proteins from the nucleus to other parts of the cell, similar to city streets?

Accepted Answer

Endoplasmic reticulum

Question 10

If a cell's ribosomes are compared to factories, what is their main product?

Accepted Answer

Endoplasmic reticulum

Question 14

If a cell's vacuole is ruptured, which of the following is the most likely consequence?

Accepted Answer

Loss of stored nutrients and water

Question 15

Which organelle is most analogous to a city's garbage disposal system, and what is its main function?

Accepted Answer

Golgi apparatus

Question 17

Which of the following best describes the function of the cytoplasm in a cell, using the city analogy?

Accepted Answer

It is the main substance that fills the cell, like the atmosphere fills a city.

Question 18

If the cell membrane becomes non-selectively permeable, which of the following is a likely outcome?

Accepted Answer

Uncontrolled movement of substances in and out of the cell

Question 19
