Photosynthesis in Flowering Plants

Where in the plant does photosynthesis primarily take place?

• Stem

• Flowers

• Leaves

• Roots

What are the raw materials required for photosynthesis?

• Oxygen and nitrogen

• Water and oxygen

• Water and carbon dioxide

• Carbon dioxide and nitrogen

What is the function of chloroplasts in photosynthesis?

• To store water

• To absorb carbon dioxide

• To convert solar energy into chemical energy

• To release oxygen

What structures within the chloroplast are responsible for absorbing solar energy?

• Stroma

• Thylakoids

• Grana

• Stomata

What is the semi-fluid interior of the chloroplast called?

• Stromata

• Thylakoid space

• Stroma

• Granal space

How is carbon dioxide transported into a leaf for photosynthesis?

• Through the roots

• Via the stem

• Absorbed by chlorophyll

• Enters through stomata

What enzyme-rich solution in the chloroplast is responsible for attaching carbon dioxide to an organic compound?

• Granal solution

• Stroma solution

• Thylakoid enzyme mix

• Mesophyll enzyme pool

What is the primary source of chemical energy for most organisms mentioned in the passage?

• Oxygen

• Water

• Glucose

• Carbon dioxide

What relationship exists between autotrophs and heterotrophs?

• Autotrophs produce oxygen for heterotrophs

• Heterotrophs produce glucose for autotrophs

• Autotrophs produce food for themselves and heterotrophs

• Heterotrophs provide raw materials for photosynthesis
