What is photosynthesis?

Back

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

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 occurs during the light-dependent reactions?

Back

During the light-dependent reactions, light energy is captured by chlorophyll and used to produce ATP and NADPH, while splitting water molecules to release oxygen.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that occur in the stroma of chloroplasts, where carbon dioxide is fixed into organic molecules, ultimately producing glucose.

Front

What is RuBP and its role in the Calvin Cycle?

Back

Ribulose bisphosphate (RuBP) is a 5-carbon sugar that combines with carbon dioxide to initiate the Calvin Cycle, allowing for the fixation of carbon.

Front

What is G3P and its significance in photosynthesis?

Back

Glyceraldehyde 3-phosphate (G3P) is a 3-carbon sugar produced in the Calvin Cycle, which can be converted into glucose and other carbohydrates.

Front

How do stomata function in photosynthesis?

Back

Stomata are tiny pores on the surface of leaves that allow for the exchange of gases; they enable carbon dioxide to enter and oxygen to exit the plant.

Front

What is the role of xylem in plants?

Back

Xylem is a type of vascular tissue that conducts water and dissolved minerals from the roots to the rest of the plant.

Front

What is the importance of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, which is essential for the light-dependent reactions of photosynthesis.

Front

What is the byproduct of photosynthesis?

Back

The byproduct of photosynthesis is oxygen, which is released into the atmosphere during the light-dependent reactions.
