Photosynthesis

Front

What is the pigment in chloroplasts that performs photosynthesis?

Back

Chlorophyll is the green pigment found in chloroplasts that captures light energy for photosynthesis.

Front

What is the main purpose of the light reactions in photosynthesis?

Back

The main purpose of the light reactions is to provide the energy and electrons for the Calvin cycle.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are oxygen and glucose.

Front

What is the interior space of the chloroplast called?

Back

The interior space of the chloroplast is called the stroma.

Front

What are the light-dependent reactions?

Back

Light-dependent reactions are the first stage of photosynthesis that convert light energy into chemical energy in the form of ATP and NADPH.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the set of chemical reactions that take place in the stroma of chloroplasts during photosynthesis, where carbon dioxide is converted into glucose.

Front

What role does water play in photosynthesis?

Back

Water provides electrons and protons during the light reactions and is split to release oxygen as a byproduct.

Front

What is the significance of chloroplasts in plant cells?

Back

Chloroplasts are the organelles where photosynthesis occurs, allowing plants to convert light energy into chemical energy.

Front

How does light intensity affect photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis up to a certain point, after which other factors may limit the process.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is a reactant in the Calvin cycle, where it is fixed into organic molecules to produce glucose.
