can someone tell me some weird things about this? i have read about them and know the scientific facts but i wanna know what is weird about them

DO YOU THINK THEY COULD TAKE OVER OUR BODIES MABEY IF WE WERE EXPOSED TO SOMETHING OR WITH TIME AND EVOLUTION

Mitochondria are the energy house of a cell. It is present in almost all eukaryotes, but not prokaryotes. what is weird about them is that actually they have their own DNA strands other than the from the cell nucleus, which means they produce their own enzymes, man. Isn't that weird?
Mitochondria do mitosis themselves intracellularly. they are not being produced by the cell actually.
Then again, actually all mtochondria are "inherited" maternally, you can only have mitochondria in your cell from your father. This is because the mitochondria in the sperm of your dad would been used up when it reaches your mum's ovum. As you know that mitochondria have their own genetic strand, your cells could produce them from the nucleus like other organnels in the cells. Aren't they weird enough?

What is wierd about mitochondria is that they colonised the human cell - i.e they were not originally of human origin. The human cell gives them shelter while they produce energy that fuels the cell, a mutully beneficial situation called symbiosis. The human gut has other such organisms - flora - that enjoy a similar relaionship. It is possible that when the mitochondria someday finds the host inhospitable, it well may colonize some other host but that process can take place only over long spans of time and the outcomes are unpredictable both for the host and the guest.

Weirdness about the mitochondria...
Mitochondria are cells within a cell. They have their own RNA and DNA and reproduce independently of their 'home' cell's reproductive life cyle.
Mitochondrial genetic instructions are transmitted to an embryo through the maternal side only so forms a direct maternal link throughout the generations. These instructions have remained largely unchanged in thousands of years and it's possible to discover how humans branched out from a common maternal ancestor through mitochondrial DNA.
It is theorized that during cellular evolution, mitochondria were originally a form of symbiotic bacteria (or bacteria-like organism) that actually lives within a host cell for mutual benefits.

Mitochondria are little compartments in each of our cells. They work to produce energy that the cell needs.
Because mitochondria have their own DNA, it is thought that they were in a symbiotic relationship with our cells ancestors. Then they became one cell like they are today. Mitochondria are passed down to children through their moms. There is an interesting study about following mitochondria DNA we inherit from our mom's all the way to the supposed "Eve", the first lady. It's featured in National Geographic. I think you can look at their website for more information that is easy to understand.

It is suspected that mitochondria were formerly a symbiotic bacterium.
They have their own DNA which, interestingly, is passed from mother to progeny and not from father to progeny, so all your mitochondria are the same as your mothers.
As for your update, I don't believe they could take over, but i guess anything is possible given enough time, though they could never survive without us (nor us without them).

The mitochondria in the cell breaks down food.

mitochondria-the powerhouses of our cells-produce the ADP needed to fuel everything our bodies do.They also have a form of DNA associated with them but it's been a while since I studied biology.

weird? well, mitochondria are forms the cell's powerhouse and it's produce adenosine triphosphate (ATP), which is an energy source for the cell..understand?

Unlike other cell components outside of the nucleus, they have their own DNA.

Mitochondria is power house of a cell.............. the ATP (Adenosine Tri Phosphate) is generated there...........
