The answer is the third one (C): endoplasmic reticulum.

Explanation for each option:

  • Plasma membrane: This is the outer boundary of the cell and does not give rise to peroxisomes. It is involved in protecting the cell and regulating what enters and exits, but not in the formation of peroxisomes.

  • Golgi: The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids for secretion or use within the cell. It is not the origin of peroxisomes.

  • Endoplasmic reticulum: Peroxisomes are believed to originate from the endoplasmic reticulum. They are formed by budding off from the ER and contain enzymes that help in the breakdown of toxic substances, such as hydrogen peroxide.

  • Nucleolus: The nucleolus is a region within the nucleus involved in ribosomal RNA synthesis and ribosome assembly. It does not play a role in the formation of peroxisomes.

In summary, peroxisomes originate from the endoplasmic reticulum and contain enzymes that help dispose of toxic substances.
