Biology Photosynthesis Review 2023

Front

What are autotrophs?

Back

Autotrophs are organisms that produce their own food using light, water, carbon dioxide, or other chemicals. Examples include plants and some bacteria.

Front

What is the Calvin cycle?

Back

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

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is a molecule that carries energy within cells. It is essential for many cellular processes, including muscle contraction and nerve impulse propagation.

Front

What are the light-dependent reactions of photosynthesis?

Back

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

Front

What are the products of photosynthesis?

Back

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

Front

What role do chloroplasts play in photosynthesis?

Back

Chloroplasts are organelles in plant cells where photosynthesis occurs, containing chlorophyll that captures light energy.

Front

What is the function of chlorophyll?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the blue and red wavelengths, to drive photosynthesis.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis, released into the atmosphere, and is essential for the respiration of most living organisms.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the atmosphere through small openings in their leaves called stomata.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.
