Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process used by plants and other autotrophs to capture light energy and convert carbon dioxide and water into oxygen and energy-rich carbohydrates such as sugars and starches.

Front

How do plants absorb carbon dioxide?

Back

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

Front

What is the role of stomata in photosynthesis?

Back

Stomata are openings on the leaf surface that allow carbon dioxide to enter and oxygen to exit during photosynthesis.

Front

What is the primary function of the roots in plants?

Back

The roots absorb water and nutrients from the soil and anchor the plant in place.

Front

What is the light-dependent reaction in photosynthesis?

Back

The light-dependent reactions are the set of reactions in photosynthesis that use energy from light to produce ATP and NADPH.

Front

What is the light-independent reaction in photosynthesis?

Back

The light-independent reactions, also known as the Calvin Cycle, do not require light and use ATP and NADPH to build high-energy compounds like sugars.

Front

What is ATP and its role in photosynthesis?

Back

ATP (adenosine triphosphate) is an energy carrier that provides energy for various cellular processes, including the light-independent reactions of photosynthesis.

Front

What is NADPH and its function in photosynthesis?

Back

NADPH (nicotinamide adenine dinucleotide phosphate) is a reducing agent that provides the high-energy electrons needed for the light-independent reactions.

Front

What are the products of photosynthesis?

Back

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

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, using ATP and NADPH to convert carbon dioxide into glucose.
