Fall ACP Review 24.25 (part 1 of 3)

Front

What does the endosymbiotic theory propose?

Back

The endosymbiotic theory suggests that eukaryotic cells evolved from prokaryotic cells through a symbiotic relationship.

Front

Which organelles are evidence for the endosymbiotic theory?

Back

Chloroplasts and mitochondria are evidence for the endosymbiotic theory due to their similarities to prokaryotic cells.

Front

What is the function of the plasma membrane?

Back

The plasma membrane regulates what enters and leaves the cell, maintains homeostasis, and holds the contents of the cell.

Front

What are cell cycle checkpoints?

Back

Cell cycle checkpoints are mechanisms that monitor the progression of the cell cycle and can repair damaged cells before they divide.

Front

What happens if cell cycle checkpoints fail?

Back

If cell cycle checkpoints fail, it can lead to uncontrolled cell division, which is a characteristic of cancer.

Front

What is cytokinesis?

Back

Cytokinesis is the process during cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is the significance of circular DNA in mitochondria and chloroplasts?

Back

The presence of circular DNA in mitochondria and chloroplasts supports the endosymbiotic theory, indicating their prokaryotic origins.

Front

How do cancer cells differ from normal cells in terms of the cell cycle?

Back

Cancer cells often bypass cell cycle checkpoints, leading to uncontrolled growth and division.

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite external changes.

Front

What role do organelles play in eukaryotic cells?

Back

Organelles perform specific functions that are essential for the cell's survival and proper functioning.
