Why do cells go through mitosis?

• To produce energy for the cell

• To reproduce, grow, and repair/replace damaged cells.

• To eliminate waste from the cell

• To increase the size of the cell without division.

What is the cell cycle?

• A process of photosynthesis in plants.

• A method of cellular respiration.

• The stages of protein synthesis in cells.

In which stage of MEIOSIS does crossing over occur?

• Metaphase I

• Anaphase II

• Prophase I

• Telophase II

What occurs during anaphase of mitosis?

• Sister chromatids are pulled apart to opposite poles of the cell.

• Chromosomes align at the cell's equator.

• Nuclear envelope begins to reform around the chromosomes.

• Cytokinesis begins, dividing the cell into two.

Which stage of cell division divides the cytoplasm?

• Mitosis

• Meiosis

• Cytokinesis

• Interphase

What is cytokinesis?

• The process that divides the cytoplasm of a parental cell into two daughter cells.

• The phase of cell division where chromosomes are separated.

• The process of DNA replication before cell division.

• The mechanism by which cells communicate with each other.

What happens during prophase of mitosis?

• Chromosomes condense, the nuclear envelope breaks down, and spindle fibers begin to form.

• Chromosomes are replicated, and the nuclear envelope remains intact.

• Spindle fibers attach to the chromosomes, and the nuclear envelope reforms.

• Chromosomes align at the cell's equator, and the nuclear envelope disintegrates.

What is the purpose of the G1 phase in the cell cycle?

• A period of cell division and mitosis.

• A period of cell growth and preparation for DNA replication.

• A phase where the cell undergoes apoptosis.

• A stage of DNA repair and damage control.
