Photosynthesis and Respiration

Front

What is the law of conservation of matter?

Back

Matter cannot be created or destroyed, only transformed from one form to another.

Front

What is photosynthesis?

Back

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

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells break down glucose and other organic molecules to produce energy in the form of ATP, using oxygen.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What are the main reactants of cellular respiration?

Back

The main reactants of cellular respiration are glucose and oxygen.

Front

What role do chloroplasts play in photosynthesis?

Back

Chloroplasts are the organelles in plant cells where photosynthesis takes place, containing chlorophyll that captures light energy.

Front

What is the significance of cyanobacteria in the history of photosynthesis?

Back

Cyanobacteria were among the first organisms to perform photosynthesis, contributing to the oxygenation of the Earth's atmosphere.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce carbon dioxide and water, creating a cycle.

Front

What are the two main stages of photosynthesis?

Back

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

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed to drive the chemical reactions in photosynthesis.
