Photosynthesis & Respiration Review

Front

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.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells break down glucose and other organic molecules to produce energy in the form of ATP, using oxygen.

Front

What are the main products of cellular respiration?

Back

The main products of cellular respiration are carbon dioxide, water, and ATP (energy).

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

How do plants absorb carbon dioxide?

Back

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

Front

What is the significance of the light-dependent reactions in photosynthesis?

Back

The light-dependent reactions convert solar energy into chemical energy (ATP and NADPH) and produce oxygen as a byproduct.

Front

What is the significance of the light-independent reactions (Calvin Cycle) in photosynthesis?

Back

The light-independent reactions (Calvin Cycle) use ATP and NADPH from the light-dependent reactions to convert carbon dioxide into glucose.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis and cellular respiration are interconnected processes; photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy.

Front

What effect does deforestation have on carbon dioxide levels?

Back

Deforestation increases carbon dioxide levels in the atmosphere due to reduced carbon absorption by trees.
