Life Science Semester One Review

Front

What is the longest step of the cell cycle?

Back

Interphase is the longest step of the cell cycle, where the cell grows and prepares for division.

Front

What is the primary energy source for photosynthesis?

Back

Sunlight is the primary energy source for photosynthesis, allowing plants to convert carbon dioxide and water into glucose.

Front

What is required for cellular respiration to occur?

Back

Glucose is needed for cellular respiration, as it is broken down to release energy.

Front

What is the shortest step in the cell cycle?

Back

Metaphase is the shortest step in the cell cycle, where chromosomes align in the center of the cell.

Front

What is a product of photosynthesis?

Back

Glucose is a product of photosynthesis, which plants use as energy.

Front

Define photosynthesis.

Back

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

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll is the pigment in plants that absorbs sunlight, facilitating the process of photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the Calvin cycle (light-independent reactions).

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
