Photosynthesis Review

How do plants store energy produced during photosynthesis?

• In the form of glucose

• In the form of starch

• In the form of proteins

• In the form of lipids

What is respiration in plants?

• A process where plants absorb sunlight to produce glucose.

• A process by which plants convert glucose and oxygen into energy, releasing carbon dioxide and water as byproducts.

• A method of water absorption through roots.

• A way for plants to reproduce and grow new leaves.

What do plants need for photosynthesis?

• Sunlight, carbon dioxide, and water

• Nitrogen, oxygen, and minerals

• Heat, carbon monoxide, and soil

• Sugar, water, and sunlight

What role does chlorophyll play in photosynthesis?

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

• Chlorophyll helps in the absorption of water from the soil.

• Chlorophyll is responsible for the production of glucose during respiration.

• Chlorophyll protects plants from harmful UV radiation.

What happens to plants in the absence of sunlight?

• They continue to grow normally.

• They cannot perform photosynthesis, leading to a lack of energy and eventual death.

• They adapt by using stored energy for growth.

• They produce more leaves to capture any available light.

What is photosynthesis?

• The process by which plants absorb water from the soil.

• 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.

• The method by which animals convert food into energy.

• The way in which plants reproduce using seeds.

What is the importance of photosynthesis to life on Earth?

• It produces carbon dioxide, which is essential for most living organisms.

• It produces oxygen, which is essential for most living organisms, and it forms the base of the food chain.

• It helps in the decomposition of organic matter.

• It regulates the temperature of the Earth.

What is the equation for photosynthesis?

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

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

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

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

What gas do plants release during photosynthesis?

• Carbon Dioxide

• Nitrogen

• Oxygen

• Hydrogen

How does light intensity affect photosynthesis?

• Higher light intensity decreases the rate of photosynthesis, leading to less oxygen and glucose production.

• Higher light intensity has no effect on the rate of photosynthesis.

• Higher light intensity increases the rate of photosynthesis, leading to more oxygen and glucose production.

• Higher light intensity only affects the color of the plants, not the rate of photosynthesis.
