The DNA in the nucleus and mitochondria are the same.
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.
A physical change could be the plantet and biosphere have a lot more O2 in the air so more organisms can survive and evolve
Tissue culture<span> is the growth of </span>tissues<span> or cells separate from the organism. This is typically facilitated via use of a liquid, semi-solid, or solid growth medium, such as broth or agar.
Hope this helps.
