Stem cells

Question 1

stem cells

Answer 1

how each cell begins.

can be unspecialised and cable of renewability

undifferentiated cells with capacity or the capability of differentiating into specialised cells.

Question 2

self renewal

Answer 2

stem cells can replicate without getting rid of their ability to differentiate. They do this by producing both a differentiated cell and a copy of themselves when they replicate

Question 3

potency in stem cells

Answer 3

the capacity to tell the difference between cell types.

Question 4

totipotent

Answer 4

totipotent cells are cells that can be differentiated into any type of cell they want or need.

Question 5

example of totipotent cells

Answer 5

zygote

the first cell produced is a zygote. they are formed once an egg or sperm cell has been fertalised so that a fetus can be built.

Question 6

pluripotent

Answer 6

a form of stem cell that can be differentiated into multiple types of cells.

Question 7

example of pluripotent

Answer 7

Embryonic stem cells.

these are found in the early stages of a developing embryo. These cells have the ability to differentiate themselves into any type of cell of the body with an exception of the placenta.

Question 8

mutlipotent

Answer 8

stem cells that can only differentiate into a limited number of specialised cells that belong to a tissue or organ that is specific

Question 9

multipotent example

Answer 9
