Why do Mitochondria are the only organelles that contain their own DNA circular and have a double membrane?
The double membrane suggests that they were subjected to phagocytosis, yet not digested. The circular DNA suggests that this organism was a free living prokaryote at one time. Both pieces of evidence suggest that a symbiotic relationship ( or a slave relationship ) was established between two simple organisms. This is called the theory of endosymbiosis. Google Lynn Margulis.
What else can I help you with?
Does bacterium have nucleus and organelles?
No, bacteria do not have a nucleus or membrane-bound organelles. They have a single circular chromosome located in the nucleoid region of the cell. Bacteria do contain ribosomes for protein synthesis, but they lack other organelles like mitochondria or endoplasmic reticulum.
Does a nuclear membrane contain mitochondria?
No, a nuclear membrane does not contain mitochondria. The nuclear membrane, also known as the nuclear envelope, surrounds the nucleus of a cell and is composed of two lipid bilayers. Mitochondria are separate organelles responsible for energy production and have their own double membrane, distinct from the nuclear membrane.
Cells contain smaller parts known as organelles. The nucleus, chloroplasts, mitochondria, and vacuoles are all examples of organelles. What do these organelles have in common?
They are all enclosed by a membrane.
What do chloroplasts and mitochondria contain genetic information in the form of?
Chloroplasts and mitochondria contain genetic information in the form of circular DNA molecules. These DNA molecules encode for a small number of genes that are involved in the functioning of these organelles.
Are membrane bound organelles in bacteria?
Bacteria do not contain membrane-bound organelles such as mitochondria or chloroplasts, as eukaryotes do. However, photosynthetic bacteria, such as cyanobacteria, may be filled with tightly packed folds of their outer membrane. The effect of these membranes is to increase the potential surface area on which photosynthesis can take place.
Do animal and plant cells both have mitochondia?
Yes. Mitochondria are membrane-bound organelles. Animal and plant cells are eukaryotes (that is, they contain membrane bound organelles). Only prokaryotes (which are mostly bacteria and don't contain membrane bound organelles) don't have mitochondria.
Does bacterium have nucleus and organelles?
No, bacteria do not have a nucleus or membrane-bound organelles. They have a single circular chromosome located in the nucleoid region of the cell. Bacteria do contain ribosomes for protein synthesis, but they lack other organelles like mitochondria or endoplasmic reticulum.
What type of cell does not contain a nucleus or membrane bound organelles?
Prokaryotic cells do not contain a nucleus or membrane-bound organelles. They have a single circular chromosome and lack membrane-bound organelles such as mitochondria or endoplasmic reticulum. Examples of prokaryotic cells include bacteria and archaea.
Does a nuclear membrane contain mitochondria?
No, a nuclear membrane does not contain mitochondria. The nuclear membrane, also known as the nuclear envelope, surrounds the nucleus of a cell and is composed of two lipid bilayers. Mitochondria are separate organelles responsible for energy production and have their own double membrane, distinct from the nuclear membrane.
Do eukaryotic cells have membrane-bound organelles?
Eukaryotes contain membrane bound organelles. Prokaryotes do not contain membrane bound organelles. However, prokaryotes do contain ribosomes which is an example of a non-membrane bound organelle.

What are the cells of monerans do not contain?
A Nucleous
Do prokaryotes contain membrane-bound organelles?
No, prokaryotes do not contain membrane-bound organelles.
What do chloroplasts and mitochondria contain genetic information in the form of?
Chloroplasts and mitochondria contain genetic information in the form of circular DNA molecules. These DNA molecules encode for a small number of genes that are involved in the functioning of these organelles.
What two other organelles besides the mitochondria contain DNA and have a double membrane?
The two other organelles that contain DNA and have a double membrane are the nucleus and the chloroplast. The nucleus contains the majority of the cell's genetic material, while chloroplasts are found in plant cells and are responsible for photosynthesis.
Do cheek cells have membrane bound organelles?
All cells have membranes. They keep the cell's cytoplasm from leaking out into the environment. Cheek cells are no different. i was going to say that but my computer wasnt working!!!!!!!!!!!!!
What is a Cell with no membrane bound nucleus or organelles?
A cell without a membrane-bound nucleus or organelles is known as a prokaryotic cell. Prokaryotic cells are typically found in bacteria and archaea, and they contain a single circular chromosome floating freely in the cytoplasm. These cells lack membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus.
