This is not exactly true, although they are similar. This is not a correct option.
The following three are correct options:
Mitochondria and chloroplasts grow independently from the cell.
This is true, and supports the idea that they previously existed as their own organisms.
Prokaryotic cells, mitochondria, and chloroplasts are all the same size.
All three organisms/organelles are roughly the same size, which supports the idea that chloroplasts and mitochondria are descendants or prokaryotes.
Mitochondria and chloroplasts contain their own ribosomes.This is true as well.
If you want to understand how interconnected our planet is—how patterns and events in one place can affect life half a world away—study El Niño.
Episodic shifts in winds and water currents across the equatorial Pacific can cause floods in the South American desert while stalling and drying up the monsoon in Indonesia and India.

Fish populations in one part of the ocean might crash, while others thrive and spread well beyond their usual territory.
