In plant cells the Golgi apparatus is particularly important for

  • A.regulating the turgor pressure of the vacuole
  • B.synthesising cell wall polysaccharides
  • C.carrying out the light reactions of photosynthesis
  • D.storing the starch made in the leaves

Answer: B

Pectins and hemicelluloses are assembled there and delivered to the wall by vesicles. Cellulose itself is the exception, being spun out at the plasma membrane instead. The two wall components are therefore made in entirely different places.
