Fotosyntese Quiz

What are the two main products of the light-dependent reactions in photosynthesis?

• Carbon Dioxide and Water

• Chlorophyll and Sunlight

• Glucose and Oxygen

• ATP and NADPH

Describe the structure of a chloroplast and its role in photosynthesis.

• The chloroplast is a double-membrane organelle containing chlorophyll, responsible for converting light energy into chemical energy during photosynthesis.

• The chloroplast is a type of bacteria that helps plants absorb water during photosynthesis.

• The chloroplast is a triple-membrane organelle that stores excess energy during photosynthesis.

• The chloroplast is a single-membrane organelle responsible for breaking down glucose in photosynthesis.

Name the primary photosynthetic pigment found in plants and explain its role in the process of photosynthesis.

• Chlorophyll

• Hemoglobin

• Melanin

• Carotene

How does temperature affect the rate of photosynthesis?

• By altering the genetic makeup of the plant

• By changing the color of the sunlight

• By influencing the activity of enzymes involved in the process.

• By affecting the amount of water available to the plant

What is the equation for photosynthesis? Write it out and explain what each component represents.

• 4CO2 + 4H2O + light energy → C4H8O4 + 4O2

• 2CO2 + 2H2O + light energy → C3H6O3 + 2O2

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

• 8CO2 + 8H2O + light energy → C12H24O12 + 8O2

Explain the role of water in the light-dependent reactions of photosynthesis.

• Water converts carbon dioxide into glucose

• Water provides electrons to the photosystem II and releases oxygen

• Water regulates the temperature of the plant

• Water absorbs light energy

What is the function of the thylakoid membrane in the process of photosynthesis?

• It is where the light-independent reactions of photosynthesis occur.

• It is where the Calvin cycle takes place.

• It is responsible for producing glucose in photosynthesis.

• It is where the light-dependent reactions of photosynthesis take place.

How do different wavelengths of light affect the rate of photosynthesis?

• It influences the absorption of light by chlorophyll and other pigments in the plant cells.

• It causes the plant to produce more oxygen

• It makes the plant grow faster

• It has no effect on the rate of photosynthesis

What are the factors that can limit the rate of photosynthesis in plants?

• Soil pH, water availability, and wind speed

• Nitrogen concentration, humidity, and soil type

• Light intensity, carbon dioxide concentration, and temperature

• Leaf size, plant age, and root depth

Describe the role of ATP and NADPH in the light-dependent reactions of photosynthesis.

• They are involved in the synthesis of glucose in the light-dependent reactions

• They regulate the opening and closing of stomata in the leaves

• They are responsible for capturing carbon dioxide from the atmosphere

• They provide the energy and reducing power needed for the Calvin cycle
