Understanding Photosynthesis

What is the process of photosynthesis?

• Photosynthesis is the process by which plants convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.

• Photosynthesis is the process of plants absorbing nutrients from the soil.

• Photosynthesis is the way in which plants breathe in carbon dioxide and release nitrogen.

• Photosynthesis is the method by which animals convert food into energy.

List the main components involved in photosynthesis.

• oxygen

• glucose

• chlorophyll

• sunlight, carbon dioxide, water

Why is sunlight important for photosynthesis?

• Sunlight is essential for photosynthesis as it provides the energy required for the conversion of carbon dioxide and water into glucose.

• Photosynthesis occurs only in the absence of sunlight.

• Sunlight is harmful to plants during photosynthesis.

• Sunlight is used to absorb nutrients from the soil.

What role does chlorophyll play in photosynthesis?

• Chlorophyll absorbs light energy for photosynthesis.

• Chlorophyll releases oxygen during photosynthesis.

• Chlorophyll acts as a nutrient for plant growth.

• Chlorophyll converts carbon dioxide into glucose.

How do plants use carbon dioxide during photosynthesis?

• Plants convert carbon dioxide into nitrogen during photosynthesis.

• Plants use carbon dioxide to absorb sunlight.

• Plants release carbon dioxide as a byproduct of photosynthesis.

• Plants use carbon dioxide to produce glucose and oxygen during photosynthesis.

What is produced as a result of photosynthesis?

• Nitrogen and hydrogen

• Carbon dioxide and water

• Glucose and oxygen

• Sugar and starch

Explain how water contributes to the photosynthesis process.

• Water is a byproduct of photosynthesis and does not play a role.

• Water contributes to photosynthesis by providing electrons and protons, and releasing oxygen during photolysis.

• Water is used to create glucose directly in the chloroplasts.

• Water absorbs carbon dioxide during photosynthesis.

What type of organisms primarily perform photosynthesis?

• Mammals and reptiles

• Fungi and viruses

• Plants, algae, and some bacteria

• Insects and arachnids

How does photosynthesis benefit the environment?

• Photosynthesis produces harmful gases.

• Photosynthesis benefits the environment by reducing carbon dioxide levels, producing oxygen, and supporting the food chain.

• Photosynthesis increases carbon dioxide levels.

• Photosynthesis has no impact on the food chain.

What is the chemical equation for photosynthesis?

• 6CO2 + 6H2O + light energy -> C6H12O6 + 6O2

• 6CO2 + 6H2O -> C6H12O6 + 6O2 + light energy

• 6O2 + 6H2O + light energy -> C6H12O6 + 6CO2

• C6H12O6 + 6O2 -> 6CO2 + 6H2O + heat energy
