Biology Photosynthesis Unit Practice Assessment

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (sugar) and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the Light Dependent Reactions (LDR) and the Calvin Cycle (Light Independent Reactions).

Front

Where do the Light Dependent Reactions occur?

Back

The Light Dependent Reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is the primary function of the Light Dependent Reactions?

Back

The primary function of the Light Dependent Reactions is to convert light energy into chemical energy in the form of ATP and NADPH.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that take place in the stroma of chloroplasts, where carbon dioxide is converted into glucose using ATP and NADPH.

Front

What is the source of carbon used in the Calvin Cycle?

Back

The source of carbon used in the Calvin Cycle is carbon dioxide (CO2) from the atmosphere.

Front

What gas is produced as a byproduct of photosynthesis?

Back

Oxygen (O2) is produced as a byproduct of photosynthesis.

Front

What happens to NADP+ and ADP produced in the Calvin Cycle?

Back

NADP+ and ADP produced in the Calvin Cycle are recycled back to the Light Dependent Reactions.
