Front

What is the main site of photosynthesis in a leaf?

Back

The mesophyll is the middle layer of the leaf where all photosynthesis takes place.

Front

What does ADP stand for in the context of photosynthesis?

Back

ADP stands for Adenosine Diphosphate, which is a molecule that plays a role in energy transfer.

Front

Which of the following is NOT required for photosynthesis to begin: sugar, water, sunlight, carbon dioxide?

Back

Sugar is not required for photosynthesis to begin.

Front

What is the function of the epidermis in a leaf?

Back

The epidermis protects the leaf and helps prevent water loss.

Front

How does light intensity affect the rate of photosynthesis?

Back

As light intensity increases, the rate of photosynthesis increases, then stabilizes.

Front

What are the two main stages of photosynthesis?

Back

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

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 chemical equation for photosynthesis?

Back

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

Front

What is the primary product of photosynthesis?

Back

The primary product of photosynthesis is glucose (C6H12O6).

Front

What gas is produced as a byproduct of photosynthesis?

Back

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