Two reasons why cells divide?

Answer 1

There are two types of cell division that a stem cell ( that is a cell that has just been created and does not have a specific function in the body yet) can undergo.

The first process of cell division that is done by all somatic (that is body cells) cells is called Mitosis. In Mitosis the DNA of a cell duplicates itself and the cell grows until it is large enough to divide. The reason a cell undergoes Mitosis is...

1) Method of Reproduction ( as seen in unicellular organisms)

2) Method of Growth ( in humans is mitosis that allows us to get bigger, as example would be that mitosis allows your skin to grow so you can get taller)

3) Method of Cell replacement ( an example would be if you skinned your arm, mitosis in your skin cells allow for new skin to grow in place of damaged skin.)

The Second process of cell division is called Meiosis. In Meiosis only cells in an organism's reproductive organs ( example is ovary for females) can create cells known as gametes ( which are cells with the half DNA). The only reason sex cells would undergo meiosis is to create gametes that when combined with gametes of the opposite sex create a new being.

Answer 2

1. To create more cells. 2. To further the total organism's development.

Answer 3

The larger a cell becomes, the more demands the cell places on its DNA. In addiction, the wastes across the cell membrane.

Answer 4

• helps cells grow and develop
• replaces old cells
• helps heal the cell -repair damage-

Answer 5

1) To create progenitors; and 2) in abundant times to share the wealth.

Answer 6

one way is the larger a cell becomes the more it demands the cell places on its DNA. another reason why is because cell divides into two new daughter cell

Answer 7

That's how they reproduce.

Answer 8

one reason is to reproduce.
