What is the source of energy for photosynthesis?

• glucose

• sunlight

• ATP

• electricity

What gas is released by plants during photosynthesis?

• Carbon dioxide (CO2)

• Hydrogen (H2)

• Nitrogen (N2)

• Oxygen (O2)

The purpose of photosynthesis is to make (a)  

Write the equation for photosynthesis (for the arrow write the word produces)

(a)  

What type of organism uses photosynthesis?

• a. plants

• b. cyanobacteria and algaes

• c. animals

• a and b

• a and c

In which organelle (part of the cell) does photosynthesis take place?

• chloroplast

• cell membrane

• mitochondria

• Golgi body

In what step of photosynthesis is carbon dioxide used?

(a)  

What molecule absorbs sunlight for photosynthesis?

• chloroplast

• thylakoid

• grana

• chlorophyll

Most plants appear green because chlorophyll

• absorbs green light

• absorbs violet light

• reflects green light

• does not absorb violet light

Where do the light-dependent reactions occur?

• thylakoid membrane

• stroma

• cytoplasm

• intermembrane space
