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 the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

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

Where do the light-dependent reactions occur?

Back

The light-dependent reactions occur in the thylakoid membranes of the chloroplasts.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the set of light-independent reactions in photosynthesis that occur in the stroma of chloroplasts, where carbon dioxide is converted into glucose.

Front

What is the significance of photosynthesis for life on Earth?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen, which is essential for the respiration of most living organisms, and it forms the base of the food chain.

Front

What are the reactants of photosynthesis?

Back

The reactants of photosynthesis are carbon dioxide and water.

Front

How does light intensity affect the rate of photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis up to a certain point, after which other factors may limit the process.

Front

What is the effect of temperature on photosynthesis?

Back

Temperature affects the rate of photosynthesis; it generally increases with temperature up to an optimal point, beyond which it may decrease due to enzyme denaturation.
