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 are autotrophs?

Back

Autotrophs are organisms that can produce their own food from inorganic substances, using light or chemical energy.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that captures the energy of sunlight, which is essential for photosynthesis.

Front

Where does the Calvin Cycle occur?

Back

The Calvin Cycle occurs in the stroma of chloroplasts.

Front

What are the products of light-dependent reactions?

Back

The products of light-dependent reactions include oxygen, ATP (energy), and NADPH (electron carrier).

Front

What is NOT a product of light-dependent reactions?

Back

Glucose (Sugar) is NOT a product of light-dependent reactions; it is produced in the Calvin Cycle.

Front

What happens to high energy electrons during photosynthesis?

Back

High energy electrons are transferred to electron carriers during photosynthesis.

Front

What is the primary function of the light-dependent reactions?

Back

The primary function of the light-dependent reactions is to convert solar energy into chemical energy in the form of ATP and NADPH.

Front

What is the significance of water in photosynthesis?

Back

Water is split during the light-dependent reactions to provide electrons, protons, and oxygen.
