Biology: Photosynthesis Review

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 oxygen and glucose.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in chloroplasts that absorbs light energy, which is essential for photosynthesis.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is a molecule that stores and provides energy for various cellular processes, similar to a fully charged battery.

Front

Where do plants obtain carbon for photosynthesis?

Back

Plants obtain carbon from inorganic carbon dioxide in the atmosphere.

Front

What are autotrophs?

Back

Autotrophs are organisms that can produce their own food from inorganic substances; examples include green plants and some bacteria.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is essential for the survival of aerobic organisms, including humans.

Front

What is the light-dependent reaction in photosynthesis?

Back

The light-dependent reactions are the first stage of photosynthesis, occurring in the thylakoid membranes, where light energy is converted into chemical energy (ATP and NADPH).

Front

What is the light-independent reaction (Calvin Cycle)?

Back

The light-independent reactions, also known as the Calvin Cycle, occur in the stroma of chloroplasts and use ATP and NADPH to convert carbon dioxide into glucose.

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis is affected by light intensity, carbon dioxide concentration, temperature, and the availability of water.
