Unit 4 - SA/Vol Ratios, Cell Cycle & Mitosis (2025)

Front

What is 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 are the stages of mitosis?

Back

The stages of mitosis are prophase, metaphase, anaphase, and telophase.

Front

What happens during prophase?

Back

During prophase, chromatin condenses into visible chromosomes, the nuclear envelope begins to dissolve, and spindle fibers start to form.

Front

What occurs during metaphase?

Back

During metaphase, chromosomes line up in the middle of the cell, and spindle fibers attach to the centromeres.

Front

What is anaphase?

Back

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

Front

What happens during telophase?

Back

During telophase, the nuclear envelope reforms around each set of chromosomes, which begin to de-condense back into chromatin.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell grows, matures, and duplicates its DNA in preparation for mitosis.

Front

What is the purpose of mitosis?

Back

The purpose of mitosis is to produce more cells for growth, repair, and maintenance of tissues.

Front

What is the cell cycle?

Back

The cell cycle is the series of events that a cell goes through as it grows and divides, including interphase and mitotic phase.

Front

What is the significance of the spindle fibers?

Back

Spindle fibers are crucial for separating sister chromatids during mitosis, ensuring each daughter cell receives the correct number of chromosomes.
