Mitochrondria of the eukaryotic cells.
As many researchers hypothesize that the old single-celled organism or the origin of the complex-celled organisms came from the endosymbiosis of the mitochrondrion organism and the prokaryotic cell. It has been said that mitochondria was an independent organism which then to have been evovled itself after planting itself inside a prokaryotic cell which aided cellular respiration and production of ATP (Adenosine Triphosphate). This then aided the prokaryotic cell to be more sophisticated and caused another change from having without a true nucleus to a eukaryotic cell with a nucleus and embedded DNA.

There are two main types of cell division—mitosis and meiosis. Which of the following is a true statement about the end products

Andrei [34K]

Mitosis happens in all types of cells. in this division, the cell will double it's number of chromosomes and then will be divided into two separated cells. so the number of chromosomes in product is equal to the number of chromosomes of the first cell

but meiosis only happens to produce gametes. the cell will be divided into two separated gametes.
in this division the number of chromosomes won't be doubled. so gametes have the half number of a normal person chromosomes.

good luck
