Yes. Called meiosis I and meiosis II.
So they can produce healthy offspring.
Because body cells need to make genetically identical daughter cells and sex cells need to make genetically unique cells with half the genetic material of the parent cell.

No, somatic (non-sex) cells have twice the number of chromosomes that sex cells have.
Sex cells.
Cause body cells have twice the chromosomes a sex cell has Body cells have 46 chromosomes and sex cells have 23 chromosomes.
It is called mitosis when regular cells divide. It is called meiosis when sex cells divide.
No. Twice.
all cells except for sex cells
miosis
meiotic division
These are called permeant cells. Examples are adult neurons, striated muscles, cardiac muscle, RBCs and cells of lens in the eye.
