Photosynthesis and Respiration

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 is the main purpose of photosynthesis?

Back

The main purpose of photosynthesis is to produce glucose, which serves as food for the plant, and to release oxygen as a byproduct.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in chloroplasts 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

What is cellular respiration?

Back

Cellular respiration is the process by which cells break down glucose and oxygen to produce energy (ATP), carbon dioxide, and water.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen to break down glucose, while anaerobic respiration occurs without oxygen.

Front

What is the formula for photosynthesis?

Back

The formula for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What is the significance of carbon in living organisms?

Back

Carbon is a fundamental element in all living organisms, forming the backbone of organic molecules such as carbohydrates, proteins, and fats.

Front

What is the role of water in photosynthesis?

Back

Water provides the hydrogen needed to form glucose and is also a source of electrons during the light-dependent reactions.
