Unit 3 Practice Exam

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide, water, and light. Oxygen is a product, not a reactant.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the phase of Meiosis where crossing-over occurs?

Back

Crossing-over occurs during prophase 1 of Meiosis.

Front

What is cancer in terms of cell division?

Back

Cancer is the uncontrolled division or uncontrolled mitosis of cells that results in malignant growth.

Front

What occurs during the M phase of the cell cycle?

Back

During the M phase, mitosis and cytokinesis occur.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy for photosynthesis.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is cytokinesis?

Back

Cytokinesis is the process that divides the cytoplasm of a parental cell into two daughter cells after mitosis or meiosis.

Front

What is the significance of crossing-over in meiosis?

Back

Crossing-over increases genetic diversity by exchanging genetic material between homologous chromosomes.
