1.1 Flashcards
what is a somatic cell
any cell in the body other than cells involved in reproduction
what are germline cells
gametes and the stem cells that divide to form gametes
what are stem cells
undifferentiated cells
what is mitosis
the process of cell division
why is mitosis important
it provides new cells for growth and repair
it maintains the diploid chromosome compliment
what is meiosis
is a type of cell division involving two revisions resulting in haploid cells which have half the chromosomes of the parent cell
how many daughter cells are produced during meiosis
four
what type of cell does meiosis produce
gametes
what is cellular differentiation
it’s the process by which a cell expresses certain genes to produce proteins specific to that type of cell
this occurs because certain genes are switched off and some are left on
what type of differentiation can embryonic stem cells do
pluripotent
what does pluripotent mean
they can become any cell
what type of cell are tissue stem cells
multi potent
give two therapeutic uses of tissue stem cells
corneal transplants and regeneration of damaged skin
describe corneal transplants and its issues
corneal tissue is regenerated from stem cells then transplanted this could be rejected
describe a regeneration of damaged skin and its issues
skin cells grown in a lab are transported into the skin or are spayed on , it could cause infection scarring and pain
