Physical Science (4th) 9 weeks Test Spring

What is the ultimate ORIGINAL source of energy for living things

• Water
• Sun
• Sugar
• Carbon Dioxide

This is where photosynthesis occurs

• Leaves
• Chloroplast
• Cell Membrane
• Nucleus

What is the main way plants get molecules into their body (inside themselves)?

• Minerals and water through the roots, Carbon dioxide through the leaves
• Glucose is sugar for energy
• Plants release oxygen
• Glucose and oxygen are used to provide food

What is the chemical formula for photosynthesis?

• H2O + C6H12O6 ---> CO2 +O2
• H2O + CO2 ---> C6H12O6 +O2
• C6H12O6 (glucose) + 6O2 (oxygen)
• H2O (water) and CO2 (carbon dioxide)

What is the chemical formula for cellular respiration?

• 6H2O + 6CO2 ---> C6H12O6 +6O2
• C6H12O6 +6O2 ---> 6H2O + 6CO2
• C6H12O6 (glucose) + 6O2 (oxygen)
• H2O (water) and CO2 (carbon dioxide)

Which of these is photosynthesis?

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

Which of these is cellular respiration?

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

Plants break the H2O (water) and CO2 (carbon dioxide) to make what during photosynthesis?

• 6H2O + 6CO2 ---> C6H12O6 +6O2
• C6H12O6 (glucose) + 6O2 (oxygen)
• H2O (water) and CO2 (carbon dioxide)

Animals break down C6H12O6 (glucose) + 6O2 (oxygen) to make what during cellular respiration?

• H2O (water) and CO2 (carbon dioxide)
• 6H2O + 6CO2 ---> C6H12O6 +6O2
• C6H12O6 (glucose) + 6O2 (oxygen)

What is the pigment in chloroplasts that performs photosynthesis?

• Chlorosynthesis
• Chlorophyll
• ADP
• Electron Transport
