Photosynthesis

What is the relationship between photosynthesis and cellular respiration?

• Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy.

• Cellular respiration produces glucose and oxygen, which are used in photosynthesis to produce energy.

• Photosynthesis and cellular respiration are unrelated processes.

• Photosynthesis occurs only in animals, while cellular respiration occurs in plants.

What gas do plants release during photosynthesis that is essential for human and animal life?

• Carbon Dioxide

• Nitrogen

• Oxygen

• Hydrogen

How do plants use the oxygen produced during photosynthesis?

• Plants absorb oxygen for growth and development.

• Plants release oxygen as a byproduct, which is used by humans and animals for respiration.

• Plants convert oxygen into carbon dioxide for photosynthesis.

• Plants store oxygen in their roots for later use.

What environmental factors can affect the rate of photosynthesis?

• Light intensity, carbon dioxide concentration, and temperature

• Soil pH, humidity, and wind speed

• Nutrient availability, soil type, and rainfall

• Altitude, latitude, and seasonal changes

What sugar is produced by plants as a result of photosynthesis?

• Fructose

• Sucrose

• Glucose

• Lactose

How does carbon dioxide enter the plant for photosynthesis?

• Through the roots of the plant.

• Through small openings called stomata.

• Through the leaves during transpiration.

• Through the flowers during pollination.

What pigment in plants captures sunlight for photosynthesis?

• Carotene

• Xanthophyll

• Chlorophyll

• Melanin

What is the chemical equation for photosynthesis?

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

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

• C6H12O6 + 6O2 -> 6CO2 + 6H2O

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

What is the process by which plants convert sunlight into chemical energy?

• Photosynthesis

• Respiration

• Transpiration

• Fermentation

What part of the plant absorbs water for photosynthesis?

• Leaves absorb water from the air.

• Stems absorb water from the soil.

• Roots absorb water from the soil.

• Flowers absorb water from the ground.
