Photosynthesis

Front

What is Photosynthesis?

Back

The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, primarily converting carbon dioxide and water into glucose and oxygen.

Front

What are the main reactants in Photosynthesis?

Back

Sunlight, carbon dioxide (CO2), and water (H2O) are the main reactants.

Front

What is the main product of Photosynthesis?

Back

Glucose (C6H12O6) and oxygen (O2) are the main products.

Front

Where does Photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in Photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs sunlight, providing the energy needed for Photosynthesis.

Front

What is the equation for Photosynthesis?

Back

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

Front

How do plants obtain carbon dioxide for Photosynthesis?

Back

Plants absorb carbon dioxide from the air through small openings in their leaves called stomata.

Front

What is the significance of oxygen produced in Photosynthesis?

Back

Oxygen produced during Photosynthesis is essential for the survival of most living organisms as it is used in cellular respiration.

Front

How do humans and animals benefit from Photosynthesis?

Back

Humans and animals benefit from Photosynthesis by consuming plants for food, which provides glucose and energy.

Front

What is the difference between Photosynthesis and Cellular Respiration?

Back

Photosynthesis converts light energy into chemical energy (glucose), while Cellular Respiration breaks down glucose to release energy.
