FYI
One bacteria cell in a colony looks like all the others.
The human body contains several hundred different cells and each possess a different set of proteins that allow it to carry out specialized activities.
All of us began life as a single fertilized egg that divided by mitosis to produce trillions of cells containing the same genes.
Key Idea #10 Following fertilization, cells divide and
become specialized for specific functions.
What do you want to be when you grow up?
There are many important jobs that grown ups do to keep our world running smoothly.
Whether doctors, teachers, builders, engineers, farmers, etc, everyone learns a specific skill which they can then use to help everyone else.
Just like people, cells specialize in important jobs.
During early embryonic development, the cells of the body became specialized for different activities in a process called cell differentiation.
How Living Things are Structured
Following fertilization, cell division produces a small cluster of cells that then differentiate by appearance and function to form the basic tissues, organs, and organ systems of multi-cellular organisms.

Specialized Cells are very different from each other in size and
structure are found in multi-celled organisms and carry out
different functions from each other are genetically programmed for a particular function have a unique structure to facilitate its function
– Cells that become liver cells express a specific set of “liver genes”
– Each cell type has specific genes that can be "switched on" or "switched off" as it carries out its particular function.
are specialized to take in nutrients, which are used to make the materials that a cell or organisms needs to survive
make up different kinds of body tissues, organs, and organ systems that function together
