Answer
ER and Golgi apparatus make and ship membrane materials.

Explanation

  • The ER makes proteins and lipids (the membrane materials).
  • These go to the Golgi apparatus to be modified and packed.
  • The Golgi packs them into vesicles.
  • Vesicles travel to the membrane and join it.
Path to the Cell Membrane
Endoplasmic reticulum (makes proteins and lipids)
↓
Golgi apparatus
Modifies and packs them into vesicles.
↓
Vesicles fuse with the cell membrane
ER makes, Golgi packs, vesicles deliver to the membrane.
