Answers

Answer:

Cell division is a process that makes our skin, tissues, muscles, sex cells. It is the building block of our body.

Explanation:

When parents cells ahs been divided into two or more than two daughter cells then it is called division of cells. The division of cells occur as a larger cell. When we talk about eukaryotic cells, these cells divided into two distinct types of the cells, the vegetative cells.

The daughter cells are the identical to the parents cells genetically. There are two types of division such as mitosis and meiosis. When parents cells divides in daughter cells and daughter cells divided further, this process called the cells cycle. The mitosis cell division occur interphase. Meiosis cell division occur in two phase meiosis I and meiosis II.
