Photosynthesis and Cellular Respiration Concepts

Mrs. Geiss explains the relationship between cellular respiration and photosynthesis. Cellular respiration occurs in animal cells, producing ATP, carbon dioxide, and water. Photosynthesis occurs in plant cells, using sunlight to produce glucose and oxygen. The processes are interconnected, forming a cycle where the outputs of one serve as inputs for the other, all driven by sunlight.

What is the primary function of cellular respiration in animal cells?

• To absorb sunlight for energy

• To convert glucose and oxygen into ATP

• To release carbon dioxide and water

• To produce glucose and oxygen

Which of the following is a product of photosynthesis?

• Carbon dioxide

• Water

• Glucose

• ATP

What role does the sun play in photosynthesis?

• It converts ATP into glucose

• It provides energy for the process

• It absorbs carbon dioxide

• It releases oxygen

Where does photosynthesis occur within the plant cell?

• Mitochondria

• Cytoplasm

• Chloroplasts

• Nucleus

What is the main purpose of ATP in animal cells?

• To absorb sunlight

• To produce glucose

• To provide energy for cellular activities

• To store genetic information

Which two substances are required for cellular respiration in animal cells?

• ATP and glucose

• Carbon dioxide and water

• Sunlight and chlorophyll

• Glucose and oxygen

What do plants release as a result of photosynthesis?

• Water

• Carbon dioxide

• Oxygen

• ATP

How do plants and animals depend on each other in the cycle of life?

• Plants provide oxygen and glucose for animals

• Animals provide glucose for plants

• Animals provide sunlight for plants

• Plants provide carbon dioxide for animals

What is the chemical formula for glucose?

• H2O

• CO2

• O2

• C6H12O6

What is the relationship between cellular respiration and photosynthesis?

• They both produce ATP directly

• They are independent processes

• They are part of a cycle where one's products are the other's reactants

• They occur only in animal cells
