What types of organisms contain mitochondria?

i think plant and animal cells both have mitochondria. Because mitochondria is the so called powerhouse of the cell, which means the cell derives its energy from the mirochondria. So plant and animal cells should have it to provide them energy.

Protozoans are single-celled organisms such as amoeba, euglena, vorticella and others, characterized by possession of a true nucleus in the cell.\n\nBacteria do not have a nucleus.  They are usually placed in the Kingdom Monera. \n\nSpecialists in single-celled organisms have found that the standard system of five kingdoms doesn't fit well with the vast diversity seen in single-celled organisms.  They use as many as 30 or 40 Kingdoms to classify all these critters.  Most of us don't care enough about single-celled critters to bother to learn the bajillions of different varieties.

Mitochondria:  Power plants\nRibosomes:  Factories (which manufacture things)\nCytoplasm:  hmmm... dunno.  Not citizens, though.

Mitochondria dont' neccessarily attach to something, but they are found inside Cytoplasm.

hes wrong (above. Prokaryotes do have organelles. THey do not have membrane bound organelles. Take for example the central vacuole of a plant. It has a membrane surrounding it, so it is not a prokaryote. Prokaryotes have ribosomes which synthesize proteins and nucleic acids to form a polypeptide chain. THey have a mitochondria for ATP etc..

In cell biology, a mitochondrion (from Greek mitos thread + khondrion granule) is an organelle found in most eukaryotic cells, including those of plants, animals, fungi, and protists. A few cells, such as the trypanosome protozoan, have a single large mitochondrion, but usually a cell has hundreds or thousands of mitochondria. The exact number of mitochondria depends on the cell's level of metabolic activity: more activity means more mitochondria. Mitochondria can occupy up to 25% of the cell's cytosol.\n\nMitochondria are sometimes described as "cellular power plants", because their primary function is to convert organic materials into energy in the form of ATP via the process of oxidative phosphorylation.

Unicellular organisms are placed in both Monera and Protista.  Also there are Archaeans that are single celled prokaryotes that are not placed in either Monera or Protista and are given their own domain called Domain Archaea.  \n\nFor the old classification system unicellular organisms are broadly placed into Monera if they lack a nucleus.  Unicellular organisms are lumped into protista if they have a nucleus and membrane bound organelles, such as mitochodria, and in some cases chloroplasts.  \n\nFor example a bacterium does not possess a nucleus.  Therefore all bacteria are placed into Monera.  \nProtista contains many different kinds of unicellular organisms such as amoeba and green algae.  All of the protists will have a nucleus and mitochondria at the very least.

mitochondria is in the cell and is used for anerobic respiration. the cell uses mitochondria for energy (ATP)

In an eukaroyotic plant cell the mitochondria is contained in the nucleus. The mitochondria are the "power plants" of the cell. There are three main classes of plant cells: Epidermis, Vascular tissue, and Ground tissue. The second type transports materials through the plant. Since the plant is larger, being a tree, perhaps the longer distance means the cells need more mitochondria to travel that longer distance. In a bush this would not be neccessary. The third type peforms photosynthesis and does starch storage and stuctural support. These types are further broken down into Parenchyma, Collenchyma, and Sclerenchyma. Since it is a larger plant and more starch needs to be stored, perhaps this explains it. More powerhouses would seems to me to be a benefit in greater starch storage for a larger plant. I did not know there could be more mitochondria in one plant cell than in another. Your statement was the first I'd heard of it.

amoeba\nand i think cynobacteria \neuglena might be not, but im not sure

Both Prokaryotic and Eukaryotic cells might contain Ribosomes.\n\nThe organelles that Eukaryotic cells have that Prokaryotic cells do not have include a true nucleus (bound by a double membrane) and usually mitochondria.  Also in some plants, chloroplasts.

Rotifers   are the only I can think of  now if it were Phylum Mollusca it could be Snails, Clams, and squids\n                                 good luck
