Photosynthesis Basics

What is the chemical equation for photosynthesis?

• 6CO2 + 6H2O -> C6H12O6 + 6O2

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

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

• CO2 + H2O + light energy -> CH4 + O2

In the photosynthesis equation, what does CO2 stand for?

• Oxygen Dioxide

• Carbon Oxide

• Carbon Dioxide

• Nitrogen Dioxide

In the photosynthesis equation, what does H2O stand for?

• Hydrogen Dioxide

• Oxygen

• Water

• Hydrogen Peroxide

What are the products of photosynthesis?

• Protein and lipids

• Carbon dioxide and water

• Nitrogen and phosphorus

• Glucose and oxygen

What are the reactants of photosynthesis?

• Hydrogen and carbon monoxide

• Oxygen and glucose

• Nitrogen and sunlight

• Carbon dioxide and water

Where does photosynthesis take place in a plant cell?

• Mitochondria

• Chloroplasts

• Endoplasmic reticulum

• Nucleus

What is the role of chlorophyll in photosynthesis?

• Chlorophyll converts carbon dioxide into glucose during photosynthesis.

• Chlorophyll releases oxygen during photosynthesis.

• Chlorophyll absorbs light energy during photosynthesis.

• Chlorophyll provides structural support to plant cells during photosynthesis.

What is the primary source of energy for photosynthesis?

• Fire

• Moonlight

• Wind

• Sunlight

What is the overall purpose of photosynthesis in plants?

• To convert sunlight into energy (glucose) for growth and survival.

• To convert water into oxygen

• To absorb nutrients from the soil

• To regulate temperature in the plant

How does photosynthesis contribute to the oxygen cycle?

• Photosynthesis contributes to the oxygen cycle by reducing the oxygen levels.

• Photosynthesis contributes to the oxygen cycle by releasing oxygen as a byproduct.

• Photosynthesis contributes to the oxygen cycle by producing carbon dioxide.

• Photosynthesis contributes to the oxygen cycle by absorbing oxygen.
