Photosynthesis/Respiration

Why is photosynthesis an essential process for life?

• It creates oxygen for animals to breathe
• Most food chains and food web depend on it
• It creates glucose for plants to use as energy
• All of these are correct

Charlotte, Harper, and Abigail were learning about photosynthesis in their science class. They learned that after photosynthesis, plants store their energy as _________ .

• Water

• Carbon Dioxide

• Glucose (sugar)

• Oxygen

A student is collecting the gas given off from a plant in bright sunlight at a temperature of 27°C. The gas being collected is probably ________.

• oxygen

• carbon dioxide

• nitrogen

• glucose

The chemical equation for photosynthesis is

• Carbon dioxide + Water + Light --> Glucose + Oxygen

• Glucose + Carbon Dioxide + Light --> Oxygen + Water

• Oxygen + Carbon Dioxide --> Light + Glucose + Water

• Light + Carbon Dioxide --> Oxygen + Water + Glucose

What is one of the three products of cellular respiration?

• nitrogen

• oxygen

• glucose

• ATP

Cellular respiration occurs in 

• chloroplasts 
• mitochondria
• golgi aparatus 
• thylakoid 

Organisms that make energy from the sun are called..

• hetertrophs 
• autotrophs 
• carbohydrates 
• consumer 

Sophia, Zoe, and Noah are studying for their biology exam. They are discussing Cellular Respiration. Sophia says that Oxygen is a reactant in Cellular Respiration. Is she correct?

• Yes, Oxygen is a reactant in Cellular Respiration

• No, Carbon Dioxide is a reactant in Cellular Respiration

• No, Water is a reactant in Cellular Respiration

• No, Sunlight is a reactant in Cellular Respiration

The reactants for cellular respiration are the carbohydrate​ ​ (a)   and ​ the gas (b)  

• Glucose
• oxygen
• carbon dioxide
• sunlight
• ATP
• Water
• Nitrogen
• phosphate

Which statement about photosynthesis is correct?

• Plants get the energy they need for photosynthesis from Glucose.

• Plants get the energy they need for photosynthesis from Oxygen.

• Plants get the energy they need for photosynthesis from sunlight.

• Plants do not require energy to perform photosynthesis.
