why are mitochondria and chloroplast called semi autonomous?
3484
Mitochondria and chloroplasts are called semi-autonomous organelles because they have their own DNA, enzymes and transport systems.
1082454
Both mitochondria and chloroplasts are sites of production of ATP, the energy currency of the cell.
1362573
The primary differences between chloroplasts and mitochondria are that chloroplasts contain pigment molecules and thylakoid molecules, while mitochondria have respiratory enzymes that chloroplasts lack.
1129843
Mitochondrion and chloroplast are the two cell organelles called as 'cell within cell'.
1338262
Prokaryotic cells, mitochondria, and chloroplasts are all the same size. and Mitochondria and chloroplasts contain their own ribosomes.
559613
1) Chloroplasts and mitochondria are similar in size to prokaryotic cells and divide by splitting (fission), just like prokaryotes. 2) Chloroplasts and mitochondria have internal structures called ribosomes, similar to those found in bacteria that allow them to make their own protieins.

If mitochondria and chloroplasts are removed from a cell, the cell cannot make any more of these organelles to replace the ones that were removed. ... Like bacteria, mitochondria and chloroplasts grow in size, duplicate their DNA and other structures, and then divide into two identical organelles.
939564
The evidence suggests that these chloroplast organelles were also once free-living bacteria. The endosymbiotic event that generated mitochondria must have happened early in the history of eukaryotes, because all eukaryotes have them. ... Since then, these organelles have become completely dependent on their host cells.

The answers to these questions have a lot to do with two important organelles: mitochondria and chloroplasts. Chloroplasts are organelles found in the broccoli's cells, along with those of other plants and algae. ... Mitochondria are found inside of your cells, along with the cells of plants.
436078
Chloroplast is only found in plants while majority of eukaryotic cells have mitochondria. Even though both organelles are found in eukaryotic cells, both mitochondria and chloroplast have characteristics often found in prokaryotic cells.
1165305
Mitochondria and chloroplasts have their own DNA genomes because they are descendants of prokaryotes that were taken up into eukaryotes a long time ago and became endosymbionts. They brought advantages to the eukaryotic host cell, such as photosynthesis and / or ATP energy generation.
892405
Mitochondria are found inside of your cells, along with the cells of plants. They convert the energy stored in molecules from the broccoli (or other fuel molecules) into a form the cell can use.
1387155
The mitochondrion and the chloroplast are both organelles that were once free-living cells. They were prokaryotes that ended up inside of other cells (host cells). They may have joined the other cell by being eaten (a process called phagocytosis), or perhaps they were parasites of that host cell.
25086
Both the chloroplast and the mitochondrion are organelles found in the cells of plants, but only mitochondria are found in animal cells. The function of chloroplasts and mitochondria is to generate energy for the cells in which they live. The structure of both organelle types includes an inner and an outer membrane.
515235
Mitochondria and chloroplasts have striking similarities to bacteria cells. They have their own DNA, which is separate from the DNA found in the nucleus of the cell. And both organelles use their DNA to produce many proteins and enzymes required for their function.
203290
Like mitochondria, chloroplasts are surrounded by two membranes. The outer membrane is permeable to small organic molecules, whereas the inner membrane is less permeable and studded with transport proteins.
22503
In eukaryotic cells, mitochondrion and chloroplast are semi autonomous organelles as it posses its own DNA. Majority of proteins needed for these organelles are coded by DNA or genes in the nucleus. Only few proteins are coded by organellar DNA. That is why these organelles are called semi autonomous organelles.
