Cell Growth & Division Video Activity

What is one reason cells cannot grow too large?

• They cannot transport materials in and out efficiently

• They lose their shape.

• They need more energy.

• They become too heavy.

What do cells do to prevent information overload and inefficient transport as they grow larger?

• They divide

• They explode

• They continue growing

• They shrink

In what phase do cells spend most of their time?

• M phase

• Cytokinesis

• Metaphase

• Interphase

What does the S phase of the cell cycle involve?

• Cell division

• Quality control

• DNA replication

• Cell growth

What occurs during the G2 phase of Interphase?

• The cell divides

• The cell explodes

• The cell checks its DNA for errors and prepares itself for cell division

• The cell duplicates its DNA so that it has two copies of genetic material

What happens during mitosis?

• Cells produce energy in the form of ATP.

• Cells grow larger.

• Chromosomes are separated into two new nuclei.

• DNA is copied.

How do animal cells divide during cytokinesis?

• They expand outward.

• They dissolve.

• They build a new cell wall down the middle.

• They pinch inward, forming a cleavage furrow.

What is the result of the cell cycle?

• A single nucleus

• A new type of cell

• Two identical daughter cells

• One large cell
