Haploid and Diploid
“Understanding
the concepts of
Haploid and Diploid”
Introducing Vocabulary
Diploid=
DIH – ployd
Haploid= HA – ployd
Haploid and Diploid
Let’s take a look at the terms first….
Diploid= Di Ploid
“Di” means “two”

Introducing Vocabulary
Gamete=
GA - meat
Somatic= So-MA-tik
Haploid and Diploid
A “Gamete” is a generic
term for a “sex cell”.
An example would be a
sperm or an egg.
Haploid and Diploid
Gametes are Haploid
in chromosome
number.
Haploid and Diploid
The number of chromosomes
that a gamete would contain
would be described
as______
Haploid
Diploid
Haploid and Diploid
“Somatic cells” refers
to every cell in the
body except gametes.

Keep Going !!!
HAlf way There !!!
Haploid and Diploid
Somatic Cells
are Diploid in
chromosome number.
Haploid and Diploid
The number of chromosomes
that a somatic cell would
contain would be described
as______
Haploid

Review
Gametes = haploid
Somatic Cells = diploid
Haploid and Diploid
Mathematically Speaking
if haploid=n,
then diploid=2n
Haploid and Diploid
Mathematically Speaking
or… haploid is ½ of diploid
or… diploid is 2x haploid
