Cell Growth

cell wall

• rigid outer layer, protects & supports, plant cells

• characteristic that can be passed on to offspring

• a flexible structure that protects, controls what goes in and out

• located in the nucleus, contains DNA

cell cycle

• a series of events occurring during the life of a cell

• change in DNA sequence

• a segment of DNA, located on the chromosome, controls specific traits

• stage of cycle, cell’s nucleus divides

interphase

• stage of cell growth, beginning of cycle

• a disease caused by cells that go through uncontrolled cell divison

• characteristic that can be passed on to offspring

• final stage of cell cycle, cytoplasm divides

mitosis

• stage of cycle, cell’s nucleus divides

• one of several tiny structures in a cell

• a series of events occurring during the life of a cell

• change in DNA sequence

12. cytokinesis

• final stage of cell cycle, cytoplasm divides

• a flexible structure that protects, controls what goes in and out

• stage of cell growth, beginning of cycle

• a disease caused by cells that go through uncontrolled cell divison

Most of the life of any cell is spent in a period of growth called

• Interphase

• Prophase

• Telophase

• Anaphase

Which of the following occurs during telophase?

• The chromosomes line up in the center of the cell.

• The sister chromatids separate.

• Two new identical nuclei are formed.

• The nucleolus disappears and the nuclear membrane breaks down.

Which best describes how a plant cell divides?

• The membrane pinches shut in the middle of the cell and the cells are split apart.

• The two cells twist apart.

• A new cell wall forms in the middle of the cell and two new cells are formed.

• Plant cells do not divide.

Which choice correctly describes the two phases of the cell cycle?

• Cells grow and develop during interphase. Cells reproduce during the mitotic phase.

• Cells grow and develop during the mitotic phase. Cells reproduce during interphase.

• The nucleus of a cell divides during interphase. The cytoplasm of a cell divides during the mitotic phase.

• The nucleus of a cell divides during the mitotic phase. The cytoplasm of a cell divides interphase.
