Exploring Photosynthesis Processes

During a biology class, Benjamin asked, "What is the primary pigment involved in photosynthesis?"

• Carotene

• Phycobilin

• Chlorophyll

• Xanthophyll

During a biology class, Ava learned about the light-dependent reactions of photosynthesis.

• The light-dependent reactions produce glucose and starch.

• The light-dependent reactions convert light energy into ATP and NADPH while releasing oxygen.

• The light-dependent reactions occur in the mitochondria of the cell.

• The light-dependent reactions use ATP and NADPH to absorb carbon dioxide.

During a science experiment, James observed the process of photosynthesis. What are the main products of the light-dependent reactions?

• Glucose, ATP, and carbon dioxide

• NADH, FADH2, and water

• ATP, NADPH, and oxygen

• Oxygen, glucose, and ATP

During a science experiment, Benjamin observed how plants use water in the process of photosynthesis.

• Water is used to store glucose during photosynthesis.

• Water absorbs sunlight for energy.

• Water provides electrons and protons for photosynthesis and releases oxygen.

• Water is a byproduct of photosynthesis.

Zoe is studying photosynthesis in her biology class. She learns about the Calvin cycle and wonders where it occurs in the plant cell.

• The Calvin cycle occurs in the stroma of chloroplasts.

• The Calvin cycle is a type of cellular respiration that happens in the cytoplasm.

• The Calvin cycle is a process that occurs in the nucleus of the cell.

• The Calvin cycle occurs in the mitochondria of cells.

How does David's garden convert carbon dioxide into glucose?

• David's plants absorb glucose from the soil.

• David's plants convert glucose into carbon dioxide during respiration.

• David's plants use sunlight to create carbon dioxide directly.

• David's plants convert carbon dioxide into glucose through photosynthesis.

During a science experiment, Aria observed how different conditions affect the rate of photosynthesis in plants. What factors can affect the rate of photosynthesis?

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

• Humidity levels

• Wind speed

• Soil pH levels

Why is photosynthesis important for life on Earth, as Abigail learned in her biology class?

• Photosynthesis is primarily responsible for water production.

• Photosynthesis is a process that generates heat energy.

• Photosynthesis occurs only in animals.

• Photosynthesis is crucial for producing oxygen and as the foundation of the food chain.
