Which of the following sets of organelles are considered part of the endomembrane system, and what is a general function shared by this system?

  • A: Mitochondria, chloroplasts, and peroxisomes; energy production.
  • B: Nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, and plasma membrane; synthesis and transport of proteins and lipids.
  • C: Ribosomes, proteasomes, and cytoskeleton; structural support and waste degradation.
  • D: Cell wall, vacuole, and plasmodesmata; osmotic regulation and nutrient storage.

Explanation

The text explicitly states: 'Many of the different membrane-bounded organelles of the eukaryotic cell are part of the endomembrane system, which includes the nuclear envelope, the endoplasmic reticulum, the Golgi apparatus, lysosomes, various kinds of vesicles and vacuoles, and the plasma membrane.' It also notes that this system 'carries out a variety of tasks in the cell, including synthesis of proteins, transport of proteins into membranes and organelles or out of the cell, metabolism and movement of lipids, and detoxification of poisons.'
