Question 26

List two differences between the structure of animal and plant cells.

Answer 26

Two structural differences of animal and plant cells are that plant cells have a cell wall surrounding the cell membrane while animal cells do not and plant cells have a much larger, central vacuole while animal cells have smaller vacuoles.

Question 27

Cigarette smoke is a carcinogen. This means that cigarette smoke can cause cells to mutate when it comes into contact with them. Describe two differences in cell division between a normal cell and a cell which has a cancer causing mutation.

Answer 27

Two differences between cell division in a normal cell and cancer cell is that cancer cells divide much more rapidly than normal cells and can’t undergo apoptosis (self-destruct).

Question 28

Describe the “main event” for anaphase.

Answer 28

The mitotic spindle rips apart the sister chromatids from the centromeres and the chromatids move further apart to prepare for telophase.

Question 29

Describe the “main event” for metaphase.

Answer 29

The sister chromatids line up at the center between the centrioles.

Question 30

Explain the function of the bronchioles.

Answer 30

Bronchioles are passages for air in the lungs that connect the bronchus to the alveoli.
