Unknown Story
טקסט Storyboard
- Instead of being digested, some of the small bacteria remained intact and began to live as symbionts (that means they live together). This is thought to be the ancestor of heterotrophic eukaryotic cells.
- eventually some of these cells engulfed the small bacteria that could do photosynthesis in addition and there was more living as symbionts.this is believed to be the ancestor autotroph eukaryote.
- It's possible that these ancient eukaryotes had an advantage in endosymbiosis, and it's also possible that the mitochondria evolved before the chromoplast. All eukaryotic cells have mitochondria, but only photosynthesis-capable cells have both mitochondria and chromoplast.
- i have a little secret to tell you all
- The bacteria that use oxygen to produce their own energy are thought to have evolved into what is now mitochondria. and the bacteria that uses sunlight to produce food, the are considered to the chloroplast that we know today.
- Firstly, both mitocondria and chloroplast have their own DNA! Their DNA differs from that found in the nucleus and is structured similarly to prokaryotic DNA—specifically, bacterial DNA. The size of mitochondria and chroloplasts is similar to that of bacteria, and when mitochondria and chroloplasts divide (which they can do independently), they divide similarly to bacteria.
- where is all the evidence u are asking for?
