Hint:

C

In which compartment of the plant cell do the light-independent reactions of photosynthesis take place?

  1. thylakoid
  2. stroma
  3. outer membrane

Hint:

B

Which statement about thylakoids in eukaryotes is not correct?

  1. Thylakoids are assembled into stacks.
  2. Thylakoids exist as a maze of folded membranes.
  3. The space surrounding thylakoids is called stroma.
  4. Thylakoids contain chlorophyll.

Hint:

B

  1. GA3P accumulation
  2. ATP and NADPH accumulation
  3. Water accumulation
  4. Carbon dioxide depletion

Hint:

B
