An animal cell had its nucleus removed by means of a fi ne glass tube. The cell was not otherwise

damaged. It was put in a solution that induces cell division. It continued to survive for a day, but did

not undergo cell division. An intact cell, used as a control, divided twice in that time. What can you

conclude from this experiment about the role of the nucleus in the cell?

• The nucleus controls the normal activity of the cell.

• The nucleus is essential for cell division.

• The nucleus is essential for life.

• The nucleus is the only part of the cell that contains DNA.

What is the likely function of these plant cells?

• Carry out photosynthesis

• Carry out respiration

• Provide support to the plant

• Transport water in the plant

Which cells are involved in the transport of substances in a living organism?

• 1 and 2

• 1 and 4

• 2 and 3

• 3 and 4

Which of the following correctly relates these specialized cells to their functions?

• A

• B

• C

• D
