What does the endosymbiont hypothesis propose?
It proposes that early eukaryotic cells acquired the precursors of mitochondria and chloroplasts by engulfing certain types of bacteria.
Pre-eukaryotic cells did not contain?
Chloroplasts and mitochondria according to the endosymbiotic theory.
Which of the following are associated with matter and energy transfers in eukaryotic cells?
chloroplasts and mitochondria
Which is used as evidence for the idea that multicellular organisms evolved from prokaryotes?
Mitochondria and chloroplasts have their own DNA
Where can DNA be found in plant cells?
DNA can be found in chromosomes located in the nucleus, as well as the mitochondria and chloroplasts

Are mitochondria and chloroplasts both found in all eukaryotic Cells?
No; Chloroplasts are only found in plant Cells.
Chloroplasts and mitochondria are?
They are eukaryotic organells.Chloroplast conducts photosynthesis.Respiration take place in mitochondria.
Pre-eukaryotic cells did not contain?
Chloroplasts and mitochondria according to the endosymbiotic theory.
Which of the following are associated with matter and energy transfers in eukaryotic cells?
chloroplasts and mitochondria
What type of cell contains mitochondria and chloroplasts?
Plant cells and eukaryotic algae that conduct photosynthesis are the two types of cells that contain choloplasts.
Which is used as evidence for the idea that multicellular organisms evolved from prokaryotes?
Mitochondria and chloroplasts have their own DNA
Where is the cells DNA largely confined?
In eukaryotic cells, DNA is confined to the nucleus, except for the DNA in the mitochondria and chloroplasts.
Is the mitrocondria in the plant cell?
Yes, a mitochondria exists in all eukaryotic cells, including plant cells. Though the chloroplasts derive the energy plants use, the mitochondria is the source of energy at night, when the chloroplasts are inoperative.
How do mitochondria and chloroplasts become part of modern eukaryotic cells?
Because of the 69 inside of the cell lol
Where can DNA be found in plant cells?
DNA can be found in chromosomes located in the nucleus, as well as the mitochondria and chloroplasts
Why do animal cells not have chloraplast?
Chloroplasts (as well as Mitochondria) are endosymbionts. This means that they are cells, living within another cell. Historically, eukaryotic cells had no mitochondria or chloroplasts (and mitochondria and chloroplasts existed by themselves outside of cells). The current hypothesis is that a cell tried to engulf a mitochondria (by phagocytosis) but failed in digesting it. Over time, some of the mitochondrial DNA (mtDNA) became part of the host cell's genome. This cell is a common ancestor to both plants and animals, which is why both have mitochondria. A cell with mitochondria then did the same thing with chloroplasts, absorbing one, and taking some of its ctDNA etc. Because not all cells that had mitochondria absorbed chloroplasts there were cells with mitochondria only, and cells with mitochondria and chloroplasts. The ones with chloroplasts evolved to become plant cells, and those without evolved to become animal cells.
