Why is cell differentiation important?
To reproduce genetically different cells to create different organs/tissue, etc, to carryout specific roles.

What is a benefit of Mitosis?
Replicate cells to carryout a specific role, replace damaged cells, allows growth.
300
The unspecialized cells from which differentiated cells develop are known as?
stem cells
400
What is the function of the mitochondria
Generates energy (ATP)

What benefits does Meiosis have?
Creates genetically different organisms, allows stronger reproduction of desirable traits.

Embryonic stem cells are pluripotent. Researchers have grown stem cells isolated from human embryos in culture. Their experiments confirmed that embryonic stem cells have the capacity to produce most cell types in the human body - meaning they are?
Pluripotent
