Mitochondria are double-membraned organelles found in the cells of most living organisms, including plants, animals, and fungi. Often referred to as the "powerhouses" of the cell, mitochondria play a crucial role in generating energy through a process called cellular respiration. This process involves converting nutrients, such as glucose and fatty acids, into adenosine triphosphate (ATP), a molecule that stores and transfers energy within cells.
Mitochondria have their own DNA, distinct from the DNA in the cell nucleus, and they reproduce independently through a process similar to bacterial binary fission. This has led to the hypothesis of endosymbiosis, which suggests that mitochondria were once free-living bacteria that were engulfed by a host cell and formed a symbiotic relationship over evolutionary time. This theory helps explain the presence of mitochondrial DNA and their ability to replicate on their own.
Besides energy production, mitochondria are also involved in various other cellular processes, including regulating calcium levels, participating in the synthesis of certain molecules, and contributing to cell signaling and apoptosis (programmed cell death). The number of mitochondria in a cell can vary based on the cell's energy needs; cells with high energy demands, like muscle cells, tend to have more mitochondria.
In summary, mitochondria are essential cellular organelles responsible for energy production and contribute to various other functions critical for the overall health and function of cells and organisms.

Thanks for the good explanation mam
Good explained..
You are amazing mam❤😊
Thank you so much
Hi, manocha academy, great video, thanks for uploading..
And please also upload vidoes on maths topics.. really enjoyed it :)
😊😊😊😊
Most welcome! Will upload more Maths videos soon!
Good teaching it's helpful for class 8 even
Amazing!
Thank you Sriritwik!
Teacher can you make a veideo of vacuoles and lysosomes
Mam is ATP a form of energy like heat or light energy or it carries energy and mam why we tell it as a energy currency does it means that we exchange atp to get energy just like we use currency to exchange goods
Pls answer
Please make a video on types of nutrition mam
Sir please upload video about Maths Trigonometry
Please explaine Abt refraction on curved surface
Refraction videos coming soon!
Tomorrow is my science exam it really helps me a lot thanku very much :-) ❤️
Can please talk about the nucleus?
Best
nice
