Answer:
In the 1960s, Lynn Magulis came up with the theory of endosymbiosis. Different evidence supports this theory that the cell organelles like chloroplasts and mitochondria were once utilized by the independent living species. Both of these organelles exhibit their own genetic material. The mitochondria cannot differentiate to produce chloroplasts and vice versa.
However, the fact that the mitochondria are found in all the cells of eukaryotes, while the chloroplast is witnessed only in certain specific cells, shows that the evolution of mitochondria took place much earlier than the chloroplasts.
It should be noted that a cell simply means the basic building block of living things and the human body has million of cells.
<h3>
What Is A Cell?</h3>
Your information is incomplete. Therefore, an overview of cells will be given. Cells provide the structure for the body and take in nutrients that are used to perform specialized functions in the body.
A cell can also be defined as the smallest unit of an organism that has a nucleus. It should be noted that the size of a cell can be measured by using an eyepiece graticule.
