Photosynthesis and Respiration Pre-Test

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs sunlight, which is essential for photosynthesis.

Front

What is the primary purpose of photosynthesis in plants?

Back

The primary purpose of photosynthesis is to convert light energy into chemical energy.

Front

What are the main functions of respiration?

Back

The main functions of respiration are to use oxygen from the air and to use glucose as energy.

Front

During photosynthesis, what happens to the energy from sunlight?

Back

The energy from sunlight is converted into chemical energy.

Front

Which pigment is primarily responsible for absorbing light during photosynthesis?

Back

Chlorophyll is the pigment primarily responsible for absorbing light.

Front

Define photosynthesis.

Back

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

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

What is respiration in living organisms?

Back

Respiration is the process of breaking down glucose to release energy, using oxygen.

Front

Explain the relationship between photosynthesis and respiration.

Back

Photosynthesis produces oxygen and glucose, which are used in respiration to release energy.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.
