Photosynthesis and Respiration

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 is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, which absorbs light energy.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

Front

What is respiration in living organisms?

Back

Respiration is the process by which cells break down glucose and other organic molecules to produce energy in the form of ATP.

Front

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to convert biochemical energy from nutrients into ATP, and then release waste products.

Front

What is the chemical equation for cellular respiration?

Back

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

Front

What role do stomata play in plants?

Back

Stomata are small openings on the surfaces of leaves that allow for gas exchange; they release oxygen and take in carbon dioxide.

Front

How do plants absorb water?

Back

Plants absorb water through their roots, which then travels up the stem to the leaves.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is glucose and why is it important for plants?

Back

Glucose is a simple sugar produced during photosynthesis; it serves as an energy source for plants and is a building block for other carbohydrates.
