8th Photosynthesis and Cell Respiration

What is the chemical that allows photosynthesis to happen?

• Carotene

• Chlorophyll

• Xanthophyll

• Anthocyanin

What is the plant trying to create during photosynthesis?

• Oxygen

• Carbon Dioxide

• Glucose

• Water

What gas is released during photosynthesis?

• Nitrogen

• Oxygen

• Carbon Dioxide

• Hydrogen

Where does photosynthesis mainly occur in a plant cell?

• Mitochondria

• Chloroplast

• Nucleus

• Ribosome

What is the role of chlorophyll in photosynthesis?

• It absorbs sunlight to convert it into chemical energy.

• It transports water in the plant.

• It stores glucose.

• It releases oxygen.

How is energy converted during photosynthesis?

• Chemical energy is converted into light energy.

• Light energy is converted into chemical energy.

• Mechanical energy is converted into thermal energy.

• Thermal energy is converted into mechanical energy.

What is the purpose of cellular respiration?

• Produce glucose

• Release oxygen

• Convert glucose into energy (ATP)

• Absorb sunlight

How is glucose used in cellular respiration?

• It is broken down to release energy as ATP.

• It is stored for future use.

• It is converted into oxygen and water.

• It is used to absorb sunlight.

Which is NOT a product of cellular respiration?

• ATP

• Water

• Oxygen

• Carbon Dioxide

What is the relationship between photosynthesis and cellular respiration?

• They are unrelated processes.

• Photosynthesis converts light energy to chemical energy; cellular respiration converts it to ATP.

• Both produce glucose as the main product.

• Cellular respiration is only in plants; photosynthesis is in all organisms.
