Cells specialize to carry out different jobs!

Amazing fact:
 Your body is made of approximately 50-80 trillion cells.
50 trillion =
You started out as an unspecialized cell – a single cell, a fertilized egg.
Really soon after an egg is fertilized by a sperm
cell, it begins to divide. The single cell divides by
mitosis until it forms a ball of cells called an
embryo. At some early point in the life of this
embryo, the cells begin to specialize.
When cells specialize, they become equipped to
take on different jobs in the body. For example,
some of the cells will become the nervous
system. Another cell will develop into the skin.
Yet another cell will become the digestive
system.
 Cells take on different jobs, so they have to be constructed specifically for
those jobs. They become specialized.
Your cells carry out all the jobs required for the life and function and health of your
body. All of the cells in your body are descended from that initial single cell, but they
may look different and they behave in different ways to get the different jobs done.
 Cells that become specially equipped to carry out a specific job are
specialized cells.
Examine some specialized animal cells. Draw and label them with
as many of the organelles and cell parts as you can. Think about
ways that you can see that the different cell types are different
from each other.
