Section 3: Cell Cycle (English)

What is the process called when new skin cells form and replace dead skin cells?

• Cell division

• Cell cycle

• Mitosis

• Cytokinesis

2. Which stage of the cell cycle involves the cell growing, making a copy of its DNA, and preparing to divide into two cells?

• Interphase

• Mitosis

• Prophase

• Telophase

How many stages are there in mitosis?

• Two

• Three

• Four

• Five

During which stage of mitosis does the cell's nucleus divide into two new nuclei?

• Prophase

• Metaphase

• Anaphase

• Telophase

What happens during cytokinesis?

• The cytoplasm divides and organelles are distributed into each of the two new cells.

• The cell membrane squeezes together around the middle of the cell.

• The cell plate forms across the middle of the cell.

• Two new plant cells are formed.

How does cell division begin in animal cells?

• Cleavage, where the cell membrane pinches together around the middle of the cell.

• Formation of a cell plate across the middle of the cell.

• Distribution of organelles into each new cell.

• Gradual development of a new cell membrane.

Which stage of mitosis is responsible for distributing one copy of DNA into each daughter cell?

• Prophase

• Metaphase

• Anaphase

• Telophase

What is interphase?

• The period before cell division where growth, DNA replication, and preparation for division occur.

• The stage where the nucleus divides into two new nuclei.

• The process where new skin cells form and replace dead skin cells.

• The stage where the cytoplasm divides and organelles are distributed.

What is the main purpose of cell division?

• To enable multicellular organisms to grow.

• To replace damaged cells.

• To reproduce.

• All of the above.

In which stage of mitosis does the cell plate form in plant cells?

• Prophase

• Metaphase

• Anaphase

• Telophase
