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.
Answer: Mitosis and meiosis are alike in that they both are a kind of cell division. They are different in that mitosis produces two cells identical to the original, while meiosis produces cells that only have half the chromosomes of the original. Meiosis ends up with haploid cells, while mitosis endup with diploid cells.
Explanation:
The mitochondria because they are the energy-producers for cells
Because the cell is considered an organelle which is a biological mechanism which consists of different parts, whereas a molecules is a single part and not a mechanism.
