Photosynthesis

Front

What is photosynthesis?

Back

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

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the green pigment that absorbs light energy for photosynthesis.

Front

What are the main products of photosynthesis?

Back

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

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed for the photosynthesis process to convert carbon dioxide and water into glucose and oxygen.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What are chloroplasts?

Back

Chloroplasts are organelles found in plant cells that are responsible for conducting photosynthesis.

Front

How does carbon dioxide affect the rate of photosynthesis?

Back

Higher levels of carbon dioxide generally increase the rate of photosynthesis, as it is one of the key reactants.

Front

What is the relationship between light intensity and the rate of photosynthesis?

Back

The rate of photosynthesis increases with light intensity up to a certain point, after which it levels off.

Front

What is chemosynthesis?

Back

Chemosynthesis is the process by which certain organisms create food using chemical energy from inorganic molecules, rather than sunlight.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis and is split to provide electrons and protons needed for the formation of glucose.
