Unit 3 SOL Review: Cell Processes

Front

What is the primary function of mitochondria in a cell?

Back

Mitochondria are the organelles responsible for cellular respiration, converting glucose and oxygen into ATP (energy) and releasing carbon dioxide and water as byproducts.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

Describe the relationship between photosynthesis and cellular respiration.

Back

Photosynthesis and cellular respiration are interconnected processes; photosynthesis converts solar energy into chemical energy (glucose), while cellular respiration converts that chemical energy into usable energy (ATP) for the cell.

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 happens to the number of chromosomes during the cell cycle?

Back

The number of chromosomes remains constant throughout the cell cycle; it doubles during DNA replication and then splits evenly during mitosis.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are the organelles where photosynthesis occurs, converting light energy into chemical energy stored in glucose.

Front

What are the main stages of cellular respiration?

Back

The main stages of cellular respiration are Glycolysis, the Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.

Front

What would happen if a cell undergoes mitosis without DNA replication?

Back

If a cell undergoes mitosis without DNA replication, the daughter cells will have only half the required DNA, leading to non-functional cells.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for growth, development, and repair in organisms, ensuring that cells divide correctly and maintain genetic stability.
