Question

the endosymbiosis theory is used to explain the origin of which two organelles?
lysosomes and peroxisomes
the golgi apparatus and vesicles
mitochondria and chloroplasts
the nucleus and the endoplasmic reticulum

Explanation:

The endosymbiosis theory proposes that mitochondria and chloroplasts originated from free - living prokaryotes that were engulfed by a larger cell. Mitochondria are thought to have been derived from aerobic bacteria, while chloroplasts are believed to have originated from photosynthetic cyanobacteria. Lysosomes, peroxisomes, the Golgi apparatus, vesicles, the nucleus, and the endoplasmic reticulum do not have their origin explained by the endosymbiosis theory. Lysosomes and peroxisomes are formed from the endomembrane system. The Golgi apparatus and vesicles are part of the endomembrane system as well. The nucleus and endoplasmic reticulum have different proposed origins related to invagination of the cell membrane rather than endosymbiosis.

Answer:

Mitochondria and chloroplasts
