Photosynthesis

Which molecule safely carries high energy electrons during Photosynthesis?

• ATP

• FADH2

• NADPH

• Coenzyme A

Why is photosynthesis important for life on Earth?

• It produces carbon dioxide necessary for respiration.

• It generates heat for the planet's climate.

• It produces oxygen and organic compounds that are the foundation of the food chain.

• It helps in the formation of fossil fuels.

What is the correct equation for PHOTOSYNTHESIS?

• light + carbon dioxide + water --> glucose + oxygen

• light + nitrogen + water --> glucose + carbon dioxide

• heat + carbon dioxide + water --> glucose + oxygen

• light + carbon + oxygen --> glucose + water

Why do leaves look green?

• They contain a molecule named chlorophyll.

• They reflect blue light more than other colors.

• They absorb all colors of light equally.

• They are made of green pigments only.

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 occurs only in plants, while photosynthesis occurs in animals.

• Photosynthesis and cellular respiration are the same process occurring in different organisms.

• Photosynthesis consumes energy, while cellular respiration produces energy.

What factors affect the rate of photosynthesis?

• Light intensity, carbon dioxide concentration, temperature, and water availability.

• Soil quality, humidity, wind speed, and light intensity.

• Oxygen levels, soil pH, temperature, and carbon dioxide concentration.

• Nutrient availability, light duration, temperature, and atmospheric pressure.

What is the function of stomata in plants?

• To absorb water from the soil

• To allow for gas exchange, including the intake of carbon dioxide

• To provide structural support to the plant

• To store nutrients for the plant

What is the light-dependent reaction in photosynthesis?

• It is the first stage of photosynthesis where sunlight is converted into chemical energy in the form of ATP and NADPH.

• It is the process where carbon dioxide is fixed into glucose during the night.

• It is the stage where water is split to release oxygen as a byproduct.

• It is the phase where plants absorb nutrients from the soil.

What is the ultimate ORIGINAL source of energy for living things?

• The Sun

• The Moon

• Volcanic Activity

• Ocean Currents

What is the significance of glucose in plants?

• Glucose is primarily used for photosynthesis.

• Glucose serves as an energy source and a building block for growth.

• Glucose is a waste product of plant metabolism.

• Glucose is used to absorb water from the soil.
