Answer:
_Mitosis_ allows the cell to grow larger and replicate its DNA in order to prepare for cell division, known as __meiosis__. The __parent cell_ is the cell that divides to become two new _daughter cells__.
Explanation:
The excerpt explains cell division. Let us define some of the terms used:
Mitosis: Mitosis is a stage in the cell cycle where a parent cell divides/replicates into two identical daughter cells. They are identical because they contain the same number of genetic information after division. Mitosis is responsible for cell growth in all somatic cells
Meiosis: Meiosis is a type of cell division in germ (reproductive) cells where the parent cell divides into two daughter cells which contain half the number of genetic information (haploid) as the parent cell.
Parent cell: This refers to the original cell that undergoes division into two or more daughter cells
Daughter cells: The daughter cells are the resulting cells produced after cell division.
For a better understanding of the whole cell division cycle, please read-up the stages contained in both the mitosis and meiosis.
<u>Answer</u>: B) centrosome - food storage
<u>Explanation</u>: The organelles known as centrosomes have the purpose of organizing microtubules and thus provide the structure of the cell. They also play a vital part during cell division by pulling the chromatids apart.
