EXAM review CH 3-5 7th

Front

What is mitosis?

Back

Mitosis is the process by which a single cell divides to produce two identical daughter cells, each with the same number of chromosomes as the original cell.

Front

What are the phases of mitosis?

Back

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

Front

What happens during prophase?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle fibers begin to form.

Front

What happens during metaphase?

Back

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

Front

What happens during anaphase?

Back

During anaphase, the sister chromatids are pulled apart to opposite poles of the cell.

Front

What happens during telophase?

Back

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

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 mitosis.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell spends most of its time, preparing for division by growing and replicating its DNA.

Front

What is cytokinesis?

Back

Cytokinesis is the process that follows mitosis, where the cytoplasm of a parental cell is divided into two daughter cells.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.
