Review- Unit 2-The cell system

Front

What is the function of the cell membrane?

Back

The cell membrane controls what enters and leaves the cell, providing protection and support.

Front

What are the main stages of mitosis?

Back

The main stages of mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for mitosis, including DNA replication.

Front

What is the role of chromosomes during cell division?

Back

Chromosomes carry genetic information and ensure that DNA is accurately copied and distributed during cell division.

Front

Define mitosis.

Back

Mitosis is the process of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What happens during prophase?

Back

During prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down.

Front

What occurs during metaphase?

Back

During metaphase, chromosomes line up at the cell's equator, and spindle fibers attach to their centromeres.

Front

What is anaphase?

Back

Anaphase is the stage where sister chromatids are pulled apart to opposite ends of the cell.

Front

What happens during telophase?

Back

During telophase, the chromosomes begin to de-condense, and the nuclear envelope re-forms around each set of chromosomes.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm divides, resulting in two separate cells.
