Stem Cells

Question 1

What’s the difference between plant cells and animal cells when their cells are able to differentiate to become specialised?

Answer 1

In animals, the ability for cells to differentiate is lost at an early stage.
A lot of plant cells don’t ever lost this ability.

Question 2

Cells that haven’t yet differentiated to become specialised are called?

Answer 2

Stem Cells

Question 3

Where do you get stem cells in humans?

Answer 3

In embryos

Question 4

Adults have stem cells too. Where are they found? And why aren’t these stem cells as useful as embryonic ones?

Answer 4

Bone Marrow.

They aren’t as versatile, meaning that they can’t differentiate into any cell, just certain ones.

Question 5

Stem cells are used to treat certain diseases already. How is sickle-cell anaemia treated?

Answer 5

Bone marrow transplants. The stem cells in the bone marrow differentiate to become blood cells, which replace the faulty old ones.

Question 6

Using stem cells to treat diseases is still a very new area of science, why?

Answer 6

More research needs to be done.
Making the cells differentiate into the correct cell requires growing them in specific conditions, it’s still a bit and hit and miss.

Question 7

Why are some people against stem cell research?

Answer 7

Some people feel that using human embryos is unethical, potential human life and all that shit
Counter-argument of that is that the rights of the person who’s suffering and could be cured by these stem cells are more important than an embryo.

Question 8

Answer 8

Unwanted.

Question 9

The 23rd Chromosomes = XX, which biological gender?

Answer 9

Female.

Question 10

The 23rd Chromosomes = XY, which biological gender?

Answer 10
