Photosynthesis & Cellular Respiration Test

Front

What is the original source of almost all the energy in most ecosystems?

Back

Sunlight

Front

Which environmental condition change would MOST directly affect the photosynthetic activity of plant cells?

Back

Carbon dioxide concentration in the air

Front

What do glucose molecules eventually break down into during cellular respiration?

Back

Energy in the form of ATP

Front

What is the process plants use to capture the sun's energy and build carbohydrates?

Back

Photosynthesis

Front

What happens to a plant's production of high-energy sugars if carbon dioxide is completely removed from its environment?

Back

No sugars will be produced.

Front

Define photosynthesis.

Back

The process by which plants capture sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is cellular respiration?

Back

The process by which cells break down glucose and other organic molecules to produce ATP.

Front

What role do chloroplasts play in photosynthesis?

Back

Chloroplasts are the organelles in plant cells where photosynthesis occurs.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to power various cellular processes.
