Photosynthesis Lesson Recap

What is the ultimate source of energy for most life on Earth?

• The moon

• Food

• The sun

• Electricity

What is photosynthesis?

• The process by which plants consume glucose

• The overall process by which sunlight, water, and carbon dioxide are chemically converted into chemical energy stored in glucose

• The process by which plants release carbon dioxide and water

• The process by which plants grow and develop without sunlight

What is glucose classified as?

• A protein

• A vitamin

• A mineral

• A sugar/carbohydrate

What are the reactants in the photosynthesis process?

• C_6H_12O_6 (glucose) and O_2 (oxygen)

• CO_2 (carbon dioxide) and H_2O (water)

• Solar energy and enzymes

• CO_2 (carbon dioxide) and O_2 (oxygen)

What are the products of the photosynthesis process?

• CO_2 (carbon dioxide) and H_2O (water)

• C_6H_12O_6 (glucose) and CO_2 (carbon dioxide)

• C_6H_12O_6 (glucose) and O_2 (oxygen)

• Solar energy and enzymes

What is the structure of grana?

• Fluid-like substance

• Single-layer membrane

• Pancake-like stacks of thylakoid membrane

• Double helix structure

What fills the space between the grana in the chloroplast?

• Cytoplasm

• Stroma

• Ribosomal fluid

• Mitochondrial matrix

Which color of light is not absorbed by chlorophyll and is instead reflected, making plants appear green?

• Blue

• Red

• Green

• Yellow

What is the purpose of the Light-Dependent Reaction in photosynthesis?

• To produce glucose directly from sunlight

• To capture energy from the sun and store it in energy-carrying molecules

• To convert carbon dioxide into oxygen

• To use ATP and NADPH to produce sugars

Which compounds carry energy from the light-dependent reactions to the light-independent reactions?

• ATP and ADP

• NADH and FADH2

• ATP and NADPH

• Glucose and Oxygen
