10.4 Cell Differentiation Flashcards
The human body contains about ___ ________ cells
100 trillion
Embryo
developmental stage, from which adult organisms are gradually produced. This is where an organism’s cells become more differentiated and specialized for particular function
Differentiation
process by which cells become more specialized
What determines the identity of a cell
differentiation
Mammals go through a flexible process of in which _____ ______ is controlled by…
cell differentiation; factors in the embryo
Have scientists discovered the processes caused by factors in the embryo?
no
Blastocyst
hollow ball of cells with a cluster of cells inside of it known as the inner cell mass
Do adult cells reach a point in which their differentiation is complete and they cannot become other cells
yes (most of them )
What type of cell goes through cell differentiation
zygote
A zygote is a _____
diploid
Diploid
2 sets of chromosomes
Haploid
one set of chromosomes
How many steps does cell differentiation have?
3
What are the steps of cell differentiation
1) Sperm fuses with the egg to form a zygote
2) 3-4 days later the zygote becomes a morula
3) 4-5 days later the zygote becomes a blastula
Cell fate map
map that depicts how and when the zygote will specialize into different special cells
Do humans have cell fate maps
no bc there are trillions of cells in the human body
