from green algea that went into land plants which now represents present day chloroplast
Mitochondria and chloroplasts are thought to have once been a free prokaryotic cell.
Photosynthetic bacteria has evolved. Symbiotic living has turned it into chloroplasts
The presence of a double membrane in chloroplasts, similar to that in prokaryotic cells, is a characteristic that suggests they may have evolved from free-living bacteria. Additionally, chloroplasts contain their own circular DNA, similar to bacteria, and replicate independently within the cell.
Because scientists have seen them.You can use a microscope to observe them.
Oxygen gas is evolved during photosynthesis as a byproduct of the light-dependent reactions in the chloroplasts of plant cells.
By various bacteria ingesting but not digesting other bacteria, most likely the precursors of mitochondria (and/or chloroplasts).
ampibians
They are thought to evolved from bacteria. Symbiotic living have turned them into organelles
90% of modern birds
Chloroplasts evolved from bacteria.They were photosynthetic bacteria.
Scientists think that penguins evolved from flying birds, similar to petrels and albatrosses, around 60 million years ago. Over time, they adapted to a more aquatic lifestyle, leading to their distinctive form and characteristics we see today.
Mitochondria and chloroplasts are thought to have once been a free prokaryotic cell.
because RNA depend to DNA.
Photosynthetic bacteria has evolved. Symbiotic living has turned it into chloroplasts
Most evolutionary scientists today do not think that amphibians evolved from the lungfish. They do share some characteristics, but the lungfish has no hint of legs.
The presence of a double membrane in chloroplasts, similar to that in prokaryotic cells, is a characteristic that suggests they may have evolved from free-living bacteria. Additionally, chloroplasts contain their own circular DNA, similar to bacteria, and replicate independently within the cell.
Mitochondria and chloroplasts have their own DNA.
