What else can I help you with?
What do both chloroplast and mitochondria have the same?
Both chloroplasts and mitochondria have double membranes and their own DNA.
What organelle have the same function as an mitochondria?
Chloroplasts have a similar function.
What organelle is responsible for converting food into energy?
Mitochondria and Chloroplasts are involved in energy conversion.
What parts of a cell do scientists think were once free-living organisms?
Mitochondria and chloroplasts are thought to have once been a free prokaryotic cell.
Do all cells have the same number of mitochondria and chloroplasts?
No, prokaryotic cells have none of either.
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.
What are factw about mitochondria and chloroplasts constitution support for the endosymbiont theorym?
There are three characteristics of mitochondria and chloroplasts that support this theory. First, both mitochondria and chloroplasts have two membranes surrounding them. Second, like prokaryotes, mitochondria and chloroplasts contain ribosomes, as well as a circular DNA molecules attached to their inner membranes. Third, mitochondria and chloroplasts are autonomous.
Which of these cellular organelles have their own DNA?
Mitochondria and chloroplasts have their own DNA. Mitochondria DNA is circular, similar to bacterial DNA, and is inherited maternally. Chloroplasts also have circular DNA and are thought to have originated from endosymbiotic relationships with ancient prokaryotes.
What organelles that have a double membrane?
Nucleus Mitochondria
Do mitochondria contain green pigment?
No they do not. They are in chloroplasts.
What organ share the same job with the mitochondria in the human body?
The chloroplasts in plant cells share a similar role to the mitochondria in that they both function as the powerhouse of the cell by producing energy through cellular respiration (for mitochondria) and photosynthesis (for chloroplasts).
What do mitochondria and chloroplasts do for a cell?
mitochondria provide power for cells chloroplasts provide food for cells by photosynthesis
