What is the role of high-energy radiation in cancer treatment?

Back

High-energy radiation is especially damaging to cancer cells because of their high rate of mitosis.

Front

What is the mitosis-promoting factor (MPF)?

Back

MPF is a complex that regulates the progression of the cell cycle, particularly the transition from G2 phase to mitosis.

Front

When does Cyclin concentration decline during the cell cycle?

Back

Cyclin concentration declines when the cell nucleus divides.

Front

How many organ systems do plants have?

Back

Plants have 2 organ systems: the root system and the shoot system.

Front

What are adult stem cells?

Back

What is the function of guard cells in plants?

Back

Guard cells control the rate of transpiration (loss of water through the leaf).

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for growth, development, and tissue repair in organisms.

Front

What is the difference between totipotent and pluripotent stem cells?

Back

Totipotent stem cells can develop into any cell type, including placental cells, while pluripotent stem cells can develop into almost any cell type but not placental cells.

Front

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

Back

The G1 phase is a period of cell growth and preparation for DNA replication.
