All living organisms are built from cells. In the cell nucleus, there is a DNA in which the genes are written, which send signals to the station what it should do. In some cases, one cell is the whole organism, as in the case of bacteria. Their cells are very simple and bacteria are considered to be the first organism on the planet Earth. On the other hand, cells of humans, animals, plants and fungi are more complex. The complexity of these cells is reflected in the presence of organoleptic structures in the station responsible for certain functions. Organele is best compared to our bodies (so those who got their name, organs are on the Latin subtle for the organ) – each has its own task and allows the cell to live.
The organelles also belong to mitochondria. They are in charge of producing energy in the cell (“cell engine”) and the first organisms did not have them, but they received energy in a different way. How did mitochondria develop?
Scientists first fascinated when they discovered that mitochondria had their own DNA (as if they were organisms for themselves). That is why today it is considered that mitochondria actually and are sometimes separate primitive organisms (bacteria) that joined the larger cell and started living in that large cell. Over millions of years of evolution, these primitive organisms have become completely dependent on the larger cell (host cell) they lived in, that they created a lasting connection. Although mitochondria were once separate organisms, today they are highly specialized in cellular organs, which is why they would no longer be able to survive outside the host cell.
It is interesting that mitochondria inherits exclusively from the mother.
