DNA – Deoxyribonucleic acid = A full set of chromosomes.
Cell
Division
 The process used for growth
and development of cells.
 Also, to replace old, dead, or
damaged cell.
 How cells divide and make
more cells = Mitosis.
Genetics – The study of genes and how they are
transferred from individuals to their offspring.

 Makes identical cells.
Mitosis
 The process of cell division
 How cells divide and make

Meiosis – The process of cell division of the sex cells.
 Mitosis -
Mitosis
vs
Meiosis
 For Growth and
making
specialized cells.
 Meiosis  For making
babies.
 Cells with specialized functions: (5).
 Muscle Cells = long & slender cells.
 Epithelial Cells = Flat, square cells of skin
and linings.
Specialized
Cells
 Fat Cells = Large, empty spaces for fat
storage.
 Nerve Cells = Long with “tails” for the
travel of nerve impulses.
 Blood Cells – Vary in shape and size
according to their function.
