Besides modifying existing molecules, which of the following macromolecules are primarily synthesized by the Golgi apparatus in plant cells?

  • A: Cellulose and starch.
  • B: Pectins and noncellulose polysaccharides.
  • C: All types of secretory proteins.
  • D: Membrane phospholipids and cholesterol.

Explanation

The text clearly states, 'Many polysaccharides secreted by cells are Golgi products. For example, pectins and certain other noncellulose polysaccharides are made in the Golgi of plant cells and then incorporated along with cellulose into their cell walls.' While the Golgi modifies other molecules, these polysaccharides are specifically mentioned as being 'made' there.
